-
-Hello friends and welcome to the tutorial on Embellishing Plots.
-
-{{{ Show the slide containing title }}}
-
-{{{ Show the slide containing the outline }}}
-
-In this tutorial, we shall look at how to modify the colour, thickness and
-linestyle of the plot. We shall then learn how to add title to the plot and
-then look at adding labels to x and y axes. we shall also look at adding
-annotations to the plot and setting the limits of axes.
-
-Let us start ipython with pylab loaded, by typing on the terminal
-
-{{{ shift to terminal and type ipython -pylab }}}
-
-::
-
-    ipython -pylab
-
-.. #[madhu: I feel the instructions should precede the actual action,
-
-since while recording we need to know before hand what we need to do]
-
-We shall first make a simple plot and start decorating it.
-
-.. #[madhu: start decorating it should be fine, with is not necessary]
-
-::
-
-    x = linspace(-2, 4, 20)
-    plot(x, sin(x))
-
-.. #[madhu: Standard is to choose between -50 to 50 or 0 to 50 with 100
-     points right?]
-
-As we can see, the default colour and the default thickness of the
-line is as decided by pylab. Wouldn't be nice if we could control
-these parameters in the plot? This is possible by passing additional
-arguments to the plot command.
-
-.. #[[Anoop: I think it will be good to rephrase the sentence]]
-.. #[madhu: Why "you" here? Shouldn't this be "we" as decided? Also I
-     added "the default" check the diff]
-
-The additional argument that we shall be passing in here now is the
-colour argument. We shall first clear the figure and plot the same in
-red colour. Hence
-
-.. #[Madhu: Note the diff for changes]
- ::
-
-    clf()
-    plot(x, sin(x), 'r')
-
-As we can see we have the same plot but now in red colour.
-
-
-To alter the thickness of the line, we use the linewidth argument in the plot
-command. Hence
-::
-
-    plot(x, cos(x), linewidth=2)
-
-produces a plot with a thicker line, to be more precise plot with line
-thickness 2.
-
-.. #[[Anoop: I guess it will be good if you say that it affects the
-   same plot, as you have not cleared the figure]]
-.. #[Madhu: To Anoop, not necessary I feel since they can see it?]
-
-{{{ Show the plot and compare the sine and cos plots }}}
-
-{{{ Pause here and try out the following exercises }}}
-
-.. #[[Anoop: is the above a context switch for the person who does the
-   recording, other wise if it an instruction to the person viewing
-   the video, then I guess the three braces can be removed.]]
-
-%% 1 %% Plot sin(x) in blue colour and with linewidth as 3
-
-{{{ continue from paused state }}}
-
-A combination of colour and linewidth would do the job for us. Hence
-::
-
-    clf()
-    plot(x, sin(x), 'b', linewidth=3)
-
-
-produces the required plot
-
-.. #[Nishanth]: I could not think of a SIMPLE recipe approach for
-             introducing linestyle. Hence the naive approach.
-
-.. #[[Anoop: I guess the recipe is fine, but would be better if you
-   add the problem statement rather than just saying "let's do a simple
-   plot"]]
-
-.. #[Madhu: It is good enough.]
-
-Occasionally we would also want to alter the style of line. Sometimes
-all we want is just a bunch of points not joined. This is possible by
-passing the linestyle argument along with or instead of the colour
-argument. Hence ::
-
-    clf()
-    plot(x, sin(x), '.')
-
-produces a plot with only points.
-
-To produce the same plot but now in blue colour, we do
-::
-
-    clf()
-    plot(x, sin(x), 'b.')
-
-Other available options can be seen in the documentation of plot.
-::
-
-    plot?
-
-{{{ Run through the documentation and show the options available }}}
-
-{{{ Show the options available for line style and colors }}}
-
-.. #[Madhu: The script needs to tell what needs to be shown or
-     explained.]
-
-{{{ Pause here and try out the following exercises }}}
-
-.. #[[Anoop: same question as above, should it be read out?]]
-
-%% 2 %% Plot the sine curve with green filled circles.
-
-{{{ continue from paused state }}}
-
-All we have to do is use a combination of linestyle and colour to acheive this.
-Hence
-::
-
-    clf()
-    plot(x, cos(x), 'go')
-
-produces the required plot.
-
-{{{ Pause here and try out the following exercises }}}
-
-%% 3 %% Plot the curve of x vs tan(x) in red dashed line and linewidth 3
-
-{{{ continue from paused state }}}
-
-.. #[Madhu: I did not understand the question]
-
-Now that we know how to produce a bare minimum plot with colour, style
-and thickness of our interest, we shall look at decorating the plot.
-
-Let us start with a plot of the function -x^2 + 4x - 5.
-::
-
-    plot(x, -x*x + 4*x - 5, 'r', linewidth=2)
-
-{{{ Show the plot window and switch back to terminal }}}
-
-We now have the plot in a colour and linewidth of our interest. As you can see,
-the figure does not have any description describing the plot.
-
-
-We will now add a title to the plot by using the title command.
-::
-
-    title("Parabolic function -x^2+4x-5")
-
-{{{ Show the plot window and point to the title }}}
-
-The figure now has a title which describes what the plot is. The
-title command as you can see, takes a string as an argument and sets
-the title accordingly.
-
-
-The formatting in title is messed and it does not look clean. You can imagine
-what would be the situation if there were fractions and more complex functions
-like log and exp. Wouldn't it be good if there was LaTex like formatting?
-
-That is also possible by adding a $sign before and after the part of the -string that should be in LaTex style. - -for instance, we can use -:: - - title("Parabolic function$-x^2+4x-5$") - -and we get the polynomial formatted properly. - -.. #[Nishanth]: Unsure if I have to give this exercise since enclosing the whole - string in LaTex style is not good - -.. #[[Anoop: I guess you can go ahead with the LaTex thing, it's - cool!]] -.. #[Madhu: Instead of saying LaTeX style you can say Typeset math - since that is how it is called as. I am not sure as well. It - doesn't really solve the purpose] - -{{{ Pause here and try out the following exercises }}} - -%% 4 %% Change the title of the figure such that the whole title is formatted - in LaTex style - -{{{ continue from the paused state }}} - -The solution is to enclose the whole string in between$. Hence,
-::
-
-    title("$Parabolic function -x^2+4x-5$")
-
-gives a title that looks neatly formatted.
-
-Although we have title, the plot is not complete without labelling x
-and y axes. Hence we shall label x-axis to "x" and y-axis to "f(x)" ::
-
-    xlabel("x")
-
-{{{ Switch to plot window and show the xlabel }}}
-
-As you can see, xlabel command takes a string as an argument,
-similar to the title command and sets it as the label to x-axis.
-
-.. #[See the diff]
-
-Similarly,
-::
-
-    ylabel("f(x)")
-
-sets the name of the y-axis as "f(x)"
-
-{{{ Show the plot window and point to ylabel and switch back to the terminal }}}
-
-{{{ Pause here and try out the following exercises }}}
-
-%% 5 %% Set the x and y labels as "x" and "f(x)" in LaTex style.
-
-{{{ continue from paused state }}}
-
-Since we need LaTex style formatting, all we have to do is enclose the string
-in between two $. Hence, -:: - - xlabel("$x$") - yalbel("$f(x)$") - -does the job for us. - -{{{ Show the plot window with clean labels }}} - -The plot is now almost complete. Except that we have still not seen how to -name the points. For example the point (2, -1) is the local maxima. We would -like to name the point accordingly. We can do this by using -:: - - annotate("local maxima", xy=(2, -1)) - -{{{ Show the annotation that has appeared on the plot }}} - -As you can see, the first argument to annotate command is the name we would -like to mark the point as and the second argument is the co-ordinates of the -point at which the name should appear. It is a sequence containing two numbers. -The first is x co-ordinate and second is y co-ordinate. - -.. #[[Anoop: I think we should tell explicitely that xy takes a - sequence or a tuple]] -.. #[Madhu: Agreed to what anoop says and also that xy= is the point - part should be rephrased I think.] - -{{{ Pause here and try out the following exercises }}} - -%% 6 %% Make an annotation called "root" at the point (-4, 0) - What happens to the first annotation ? - -{{{ continue from paused state }}} - -As we can see, every annotate command makes a new annotation on the figure. - -Now we have everything we need to decorate a plot. but the plot would be -incomplete if we can not set the limits of axes. This is possible using the -button on the plot window. - -we shall look at how to get and set them from the script. -:: - - xlim() - ylim() - -We see that xlim function returns the current x axis limits and ylim -function returns the current y-axis limits. - -Let us look at how to set the limits. -:: - - xlim(-4, 5) - -We see the limits of x-axis are now set to -4 and 5. -Similarly -:: - - ylim(-15, 2) - -sets the limits of y-axis appropriately. - -{{{ Pause here and try out the following exercises }}} - -%% 7 %% Set the limits of axes such that the area of interest is the rectangle - (-1, -15) and (3, 0) - -{{{ continue from paused state }}} - -As we can see, the lower upper limits of x-axis in the question are -1 and 3. -The limits of y-axis are -15 and 0. - -:: - - xlim(-1, 3) - ylim(-15, 0) - -Gives us the required rectangle. - -{{{ Show summary slide }}} - -we have looked at - - * Modifying the attributes of plot by passing additional arguments - * How to add title - * How to incorporate LaTex style formatting - * How to label x and y axes - * How to add annotations - * How to set the limits of axes - -{{{ Show the "sponsored by FOSSEE" slide }}} - -.. #[Nishanth]: Will add this line after all of us fix on one. - -This tutorial was created as a part of FOSSEE project, NME ICT, MHRD India - -Hope you have enjoyed and found it useful. -Thankyou - -Questions -========= - - 1.

+
+{{{ Show the plot window with clean labels }}}
+
+The plot is now almost complete. Except that we have still not seen how to
+name the points. For example the point (2, -1) is the local maxima. We would

+::
+
+    annotate("local maxima", xy=(2, -1))

+
+As we can see, every annotate command makes a new annotation on the figure.
+
+Now we have everything we need to decorate a plot. but the plot would be
+incomplete if we can not set the limits of axes. This is possible using the
+button on the plot window.
+
+we shall look at how to get and set them from the script.
+::
+
+    xlim()
+    ylim()
+
+We see that xlim function returns the current x axis limits and ylim
+function returns the current y-axis limits.
+
+Let us look at how to set the limits.
+::
+
+    xlim(-4, 5)
+
+We see the limits of x-axis are now set to -4 and 5.
+Similarly
+::
+
+    ylim(-15, 2)
+
+sets the limits of y-axis appropriately.
+
+{{{ Pause here and try out the following exercises }}}
+
+%% 7 %% Set the limits of axes such that the area of interest is the rectangle
+        (-1, -15) and (3, 0)
+
+{{{ continue from paused state }}}
+
+As we can see, the lower upper limits of x-axis in the question are -1 and 3.
+The limits of y-axis are -15 and 0.
+
+::
+
+    xlim(-1, 3)
+    ylim(-15, 0)
+
+Gives us the required rectangle.
+
+{{{ Show summary slide }}}
