Image as background and values plotted on the image

[Eric Kok]

I received the following customer request. Our customer provides images of objects: buildings, man-made objects in the landscape. They would like to plot values from a database on this background image on custom-places on this image. I am assuming with thresholds that influence the colour of the values. Is something like this possible?

Hi Eric, 

 

For your requirement can be achieved by creating a diagram widget as custom widget with the image as background of the diagram widget and plot values on the diagram widget. But doing resizing operations to the custom diagram widget, background image will not be resized automatically since the background image size is static.   

 

We will work on this and get back to you with example custom widget in a couple of days and we appreciate your patience.
