Question

I’m having some difficulty with the MSFT .Net Charts API. I want the chart images to not be deleted

    deleteAfterServicing=false

and I want them to be over written every 15 min

    timeout=900

But instead what happens is every time I load the chart it just creates a new file.
If I set deleteAfterServicing to true then the files do not persist (they are immediately deleted)

Here is my entire key

<add key="ChartImageHandler" value="storage=file;timeout=900;dir=D:\StatTick\tempCharts\;deleteAfterServicing=false"/>

Thanks in advance!

It seems that this is a limitation of the API. Either way I re-wrote this so that I generate the chart in code use .SaveImage() to save it where I want, this way I can overwrite it at whatever interval I want.
