Still trying to figure this one out…

I am trying to periodically add one point to a PtTrend widget (Photon

2.01 Alpha). I set it up in PhAB so the plot min is -100 and the max is

+100. Then I execute the following code:

int datavalue[1];

datavalue[0] = some value between -60 and +60

PtSetArg(&args, Pt_ARG_TREND_DATA, datavalue, 1); //also tried

&datavalue

err = PtSetResources(ABW_nameof trendwidget, 1, args);

err returns 0, but the trend is always plotted right down the center of

the widget, where I assume zero is. Can someone tell me what I am doing

wrong? Thanks.
