Position Annotation directly after a color range

[hdoody]

I am using a linear guage from Fusion Widgets version 3, and would like to position an image at the end of a color range within a linear guage.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

 

The color range uses values to position it on the guage.

The annotation uses x,y coordinates to position it on the guage.

 

I was wondering if there is a way to calculate the x position from a minValue or a maxValue you enter into a color range?

 

 

I have a guage that goes from: -2,000 up to 2,000 ---- this range may vary, depending upon the value, but 0 is always in the middle of that range.

I am setting the guage color to be red from value 0 up to value 500

That value is also dynamic, and I would like to take that dynamic value --- 500  in this case --- and position an image right at the end of that location in the guage.

Well, 500 is a value rather than the numeric x value that an annotation uses.

Is there any simple formula to convert a point value or color range value to an actual x position on the guage?

Or, is there an easier way to position an image at the end of a color range?

 

Below is a sample guage where I am attempting this --- the php variable:  $position  is where I would store the result of the calculation of the x position:

Hi,

 

 

 

Since the co-ordinates for color range are dynamically generated based on other elements to be rendered in the chart, there isn't a direct way to map that to annotation x/y. The only feasible way would be to modify the source code to embed the images at right location.
