How can I reduce the number of temporary image files generated by the Dundas Chart for Asp.net control?

When you use the Dundas Chart for Asp.net control to generate a chart, each chart is saved as an image file. In this way, when browsing more, there are more useless image files? How can we prevent it from generating so many temporary files?

Dundas Chart is too fancy, and there is no need to do that,

You may be using version 5.0. In this version, its image is set with a limit. You can find it in the attribute. When the image it generates reaches that value, it will not be generated, but will be overwritten.
In addition, you can disable attribute settings to store the generated images. I have asked about the specific method on the official website before, and I forget it. You can go to the FAQ on the official website to find out.

Version 5.5 does not have this problem.

There is a choice, with the parameter rendertype = "binarystreaming", directly output as an image, and then reference this aspx on other pages
