Hello,
Embedded Wizard support for gradients is limited. Please see the section Specify the color of the stroked path. The support limits to a simple linear interpolation between four color values specified at the corners of the area enclosing an image (e.g. an area enclosing a drawn arc). Your approach expects an interpolation along the drawn path and is not supported.
What you can do?
I assume you display the arc by using the Stroked Path view, right? In this case:
- replace the single Stroked Path view by 4 views arranged in two columns and two rows.
- Connect all 4 views to the same Path Data object containing the arc. All 4 views will thus display exact the same section of the arc.
- Adjust the Offset properties of each view individually, so the sections displayed in the views do compose the complete arc.
- Now you have 4 views. Each view can be configured with 4 individual color value. Since the views do connect at their edges, you have in total 9 color values you can individually specify for the image.
- Depending on the arc length you can calculate which colors should appear in which view. Calculate bthe colors and configure the views accordingly.
This is just a workaround. Without knowing your exact design it is difficult to say, whether it will work as expected. Can you provide a screenshot demonstrating the expected color gradient?
Another approach would be to use images for this purpose. This means, you create the images with a graphic editor and import them in Embedded Wizard. In this case you need as many images as steps in the arcs.
