Invalid temp images directory in chart handler configuration

Question

I am using highchart and I am getting this error only when I run my website on IIS server in intranet network. Instead it works fine in the development server (visual studio 2012)

Invalid temp images directory in chart handler configuration [c:\TempImageFiles]. Please edit the web.config file. The CharImageHandler key, Dir value must point to a valid directory. The directory is required for temporary image storage when storage mode equals file system.

Stack trace

[DirectoryNotFoundException: Invalid temp images directory in chart handler configuration [c:\TempImageFiles\]. Please edit the web.config file.

Answer 1

Previously it was like this in web.config

<add key="ChartImageHandler" value="storage=file;timeout=20; dir=c:\TempImageFiles/;" />

I removed the directory location

<add key="ChartImageHandler" value="storage=file;timeout=20;" />

And the problem solved.

Answer 2

Check if that folder exists on your server and give read/write permission to the user of the application pool your site is running for that folder.

Or you can simple move that temp folder inside the site root Es: "~/temp" and configure highchart to use that folder.

Or you can change your ChartImageHandler from

<add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:\TempImageFiles\;" />

To

<add key="ChartImageHandler" value="storage=file;timeout=20;" />

So he will use the default windows temp directory
