I have a strange issues with plotting values in NI Measurement studio WPF graphs. The issue occurs when the axis is log based and the value on the axis spans from below 1 to above 1 (i.e. 0.001 to 1000). The graph automatically change the x-axis lower to limit to 1. The behaviour is similar to the one reported here (http://forums.ni.com/t5/Measurement-Studio-for-NET/log-scale-won-t-scale-to-show-small-values/m-p/27...) but in my case none of the value plotted is 0 or less than 0 and the axis lower limit is set higher than 0.
The code below will reproduce the issue:
Point[] pt=new Point[100];
for(int i=1; i <= 100;i++)
{
pt[i-1] = new Point(0.1 * i, i)
}
Plot pl = new Plot("test");
pl.Data=pt;
graph.Plots.Add(pl);
Where the x-axis of graph is log10 scale (and the limits are set to {0.1, 10} in the .xaml code) and y-axis is linear (doesn't matter the scale really). The graph automatically set the x-axis to 1 and this can be changed to 0.1 but this this is reset again to 1 if the graph visible property changed.
This behavious does not occur if all the x-axis values are below 1 or above 1 i.e. the code below will plot correctly and the axis doesn't reset to 1 etc:
Point[] pt=new Point[100];
for(int i=1; i <= 100;i++)
{
pt[i-1] = new Point(0.001 * i, i)
}
Plot pl = new Plot("test");
pl.Data=pt;
graph.Plots.Add(pl);
Does anyone know why this is behaving like this and what can be done to correct this?
