|
| The <b>gnuplot</b> tag allows an author to design a plot which can |
|
| be created on the fly. This is intended for use in homework problems |
|
| where each student needs to see a distinct plot. It can be used in |
|
| conjunction with a <b>script</b> tag to generate random plots. |
|
| </p><p> |
|
| A <b>gnuplot</b> tag can contain the following sub-tags: |
|
| </p> |
|
| <dl> |
|
| <dt> Plot Label |
|
| <dd> Allows you to place text at a given (x,y) coordinate on the plot. |
|
| <dt> Plot Title |
|
| <dd> The title of the plot |
|
| <dt> Plot Xlabel |
|
| <dd> The label on the horizontal axis of the plot |
|
| <dt> Plot Ylabel |
|
| <dd> The label on the vertical axis of the plot |
|
| <dt> Plot Axes |
|
| <dd> allows specification of the x and y ranges displayed in the plot |
|
| <dt> Plot Key |
|
| <dd> Lists the functions displayed in the plot. |
|
| <dt> Plot Curve |
|
| <dd> Sets the data used in the plot. |
|
| <dt> Plot Tics |
|
| <dd> Allows specification of the x and y coordinate 'tics' on the axes. |
|
| This is mostly used to adjust the grid lines when a grid is displayed. |
|
| </dl> |
|
| If you are having trouble with your plot, please read the help |
|
| available on Plot Curve. |

| The <b>curve</b> tag is where you set the data to be plotted by gnuplot. |
|
| There are two ways of entering the information: |
|
| <dl> |
|
| <dt> Curve Data |
|
| <dd> Using a <b>data</b> tag you can specify the numbers used to produce |
|
| the plot. |
|
| <p> |
|
| By default, two <b>data</b> tags will be available in a plot. The |
|
| first will specify X coordinates of the data and the second will |
|
| give the Y coordinates of the data. When working with a linestyle that |
|
| requires more than two data sets, inserting another <b>data</b> tag is |
|
| required. Unfortunately, you must make sure the <b>data</b> tags appear |
|
| in the order gnuplot expects the data. |
|
| </p><p> |
|
| Specifying the data should usually be done with a perl variable or array, |
|
| such as \@Xdata and \@Ydata. You may also specify numerical data seperated |
|
| by commas. Again, the order of the <b>data</b> tags is important. The |
|
| first tag will be the X data and the second will be the Y data. |
|
| </p> |
|
| <dt> Curve Function |
|
| <dd> The <b>function</b> tag allows you to specify the curve to be |
|
| plotted as a formula that gnuplot can understand. <b>Be careful using this |
|
| tag.</b> It is surprisingly easy to give gnuplot a function it cannot deal |
|
| with properly. Be explicit: 2*sin(2*3.141592*x/4) will work but |
|
| 2sin(2*3.141592x/4) will not. If you do not receive any errors in the |
|
| gnuplot data but still do not have an image produced, it is likely there |
|
| is an error in your <b>function</b> tag. |
