<para>A new feature in &kde; 3.4 is that you can write scrips for &kmplot; with &DCOP;. For example, if you want to define a new function <userinput>f(x)=2sin x+3cos x</userinput>, set its line width to 20 and then draw it, you type in a console:</para>
|
||
|
|
<para><command>dcop kmplot-PID Parser addFunction "f(x)=2sin x+3cos x"</command>
|
||
|
|
As a result, the new function's id number will be returned, or -1 if the function could not be defined.</para>
|
||
|
|
<para><command>>dcop kmplot-PID Parser setFunctionFLineWidth 20 ID</command>
|
||
|
|
This command sets the function with the id number ID the line width to 20.</para>
|
||
|
|
<para><command>>dcop kmplot-PID View drawPlot</command>
|
||
|
|
This command repaints the window so that the function get visible.</para>
