Scale graph

[bandersen]

Hi

I am using the following fuctions to draw a graph in visual studio by using the labview include libs:

InitCVIRTE();

NewPanel();

NewCtrl();

DisplayPanel();

SetAxisScalingMode();

PlotStripChart();

I can change the size of the background window by changing the values in the function NewPanel, but I don´t know how to change the size of the graph. I want it to fill most of the screen. I have also tryed with the function SetAxisScalingMode but it did not change the size og the graph it only changed the Scaling.

How do I change the size og the graph?

You should use SetCtrlAttribute with ATTR_HEIGHT and ATTR_WIDTH to change the graph dimensions. SetAxisScalingMode is only aimed to alter the axis scales, as you already observed, leaving control dimensions untouched. Axis scales are not affected by changes in control dimensions: however, you may observe changes in tick marks of the scale when chenging graph size if you are using automatic divisions in the graph.

Hi

Ok, sorry but I don´t understand the "controlAttribute integer". What should I choose to make my graph bigger?

I have to choose  one of the following:

ControAttribute parameter specifies which attribute you want to set. In your case you must call SetCtrlAttribute twice: one time with ATTR_WIDTH attribute, the other with ATTR_HEIGHT.

Dimensions are expressed in pixels.
