Problém s úpravou barvy/velikosti v arcGIS Symbology v Power BI

Question

V rámci tooltipu Vrstvy>>Symbology>>Color&Size>>Counts and Amounts (color)>>Style Options

Uvnitř výše uvedené cesty pro mou mapu arcGIS v Power BI je tlačítko Classify Data zašedlé a brání mi v ručním nastavení počtu barevných tříd a metody. Také nemohu upravit posuvné rozsahy. Jakmile se objeví ruka a kliknu pro posunutí, celá možnost classify data zmizí. Jediný způsob, jak ji získat zpět, je odebrat data z políček a znovu je přidat.

Číselný rozsah mých dat je poměrně malý, takže je nezbytné přidat několik tříd a barev. Aktuální rozsah dat je od -2.0000 do 1.0000.

Jak mohu tuto možnost aktivovat? Také jsem vyzkoušel široký rozsah testovacích dat, abych zjistil, zda to něco změní, ale nezměnilo. V polích velikosti a barvy v Power BI mám číselné hodnoty.

also, the classify data is grayed out so i cant add additional classes.  This is a Above and Below theme, but i've tried them all and cant get to work.

Thank you.  I am actually using the same data field for both color and size.  What i cant figure out is why can i not add as many conditional formats for color as i want?  Here is an example.  % change Velocity is 8.8%.  this is considered good.  The line is colored a light shade of yellow/green but i have it set to display as dark green.   what am i missing?

@MarkFleet - Hello there! My name is Anthony and I am a product engineer on the ArcGIS for Power BI visual. I was looking over this issue and I would like to help out if I can!

This particular option and settings are disabled by design. As an example, using both size and color is a good way to show count information (size) shaded by a rate (color). Another example using both size and color can be:

The Color and Size style is also useful for mapping a single attribute in the data using different colors and proportional symbol pairs to show values that are above and below a key value—for example, where childhood obesity rates are above and below the national average.

However, you can style the data using Color and Size somewhat differently depending on what value you drop in the field well first.

Here is an example of a numeric value being added to the size field-well first and then color. In this instance, I have classified the size value into different groups or buckets, while the color ramp is continuous.

Let me know if this helps!
