I'm trying to get a trend widget to display the legend values in exponential format [WinCC OA 3.16 P026], but it seems this is not possible. From the documentation, we can see that the function curveLegendFormat would have been meant for this, but the format parameter is described as
This does not include the type. If you try to pass "%g" or "%e", it will keep the default value of "%6.2f" (as returned from getting the value of curveLegendFormat and as displayed in the trend legend). If you try to pass "%15.3e", it will set "%15.3f".The format string, for example, "%6.2" (value with two decimal places).
Assuming this is indeed a limitation of WinCC OA, has anyone come up with a work around for this?
