Grid Trend - Ref value

[AMRPatricio]

Hi All,
I plan to implement something and I would like to have your opinion: for my trend I have different Ref values/lines that I would like to see represented on the grid. I can see that it is possible to define a ref value for the grid and also the spacing below/above which is going to set the number of grid lines that are shown above/below the reference value .
But on my specific case the grid lines that I want to represent do not follow a constant distance from the ref value. For example assuming the ref value is 500, I want to represent the following grid lines:450(90%refvalue), 300(60%refvalue), 150(30%refvalue)

Any ideas?

Thanks in advance.

Antonio

You could add 3 extra lines to your trend. You do not connect these lines to a datapoint but instead fill them via scripting.

Or,
* Make some extra lines
* Add code to the 'scroll' event of the trend widget
* In the scroll event-> Use scripting to add fake values to your lines

Hope this helps

share the fun

Hi Frenk,
thanks for reply.

"You could add 3 extra lines to your trend. You do not connect these lines to a datapoint but instead fill them via scripting.", I guess you meant "curves" not lines?

I want to represent grid lines, which represent thresholds from my curve.

Thanks,
Antonio

So... ?

Just make 3 fake lines and call them 'grid1', 'grid2' and 'grid3'.
Instead of connecting them to a datapoint YOU add the points to the lines by scripting.

Use "curveMarking" to define extra reference lines (as many as you like) per curve.

Hi Martin,
thank you for your idea but "curveMarking" only allow me to create one single line per curve(or a range), not multiple single lines.

Thanks

You are wrong.
Try the following example code:

Code: Select all

  this.curveMarking("#1_2", 1, 100, 100, "red", "[dashed,oneColor,JoinMiter,CapButt,0]");
  this.curveMarking("#1_2", 2, 120, 120, "red", "[dashed,oneColor,JoinMiter,CapButt,0]");
  this.curveMarking("#1_2", 3, 160, 160, "red", "[dashed,oneColor,JoinMiter,CapButt,0]");

Thanks for your help Martin .
