Problem with Stripchart

Hi,

I am having a problem using a strip chart and two numeric controls.

I am running LabWindows/CVI 2010 Version 10.0.1 (434)

I have searched the database but did not find anything close to the problem I am having.

It's actually quite simple.

As you can see from the graph below I have a strip chart and two numeric controls.

The numeric controls are meant to adjust the starting and ending values

The numeric; "shot count start" works flawlessly.

The ending numeric called; "Shot Count  End"  has its value written into the starting X position of the strip chart when it changes. (The only time I change this X value is when the starting numeric changes. When the ending numeric  value changes all I do is change the number of points to display.)

I have placed the steps I use for each case below the diagram

When a change is made to the starting numeric

1. Clear Chart Data                                                ClearStripChart ( panel, TRI_PANEL_CHART)

2. Change set number of points                             SetCtrlAttribute( panel, TRI_PANEL_CHART, ATTR_POINTS_PER_SCREEN, numberOfPoints);

3. Set the new X offset                                           SetCtrlAttribute( panel, TRI_PANEL_CHART, ATTR_XAXIS_OFFSET, (double)newStart);

4. Draw Chart

When a change is made to the ending numeric

1. Clear Chart Data                                                ClearStripChart ( panel, TRI_PANEL_CHART)

2. Change set number of points                             SetCtrlAttribute( panel, TRI_PANEL_CHART, ATTR_POINTS_PER_SCREEN, numberOfPoints);

3. Draw Chart

I last thing I attempted was to make the callback for the numerics the same.

Here is a graph of the crazy update when  change the ending numeric

Thanks in advance for any suggestions
