Hello, Luca.

Using the trial version, while I changed from a style of Stimulsoft to a style saved in a component style, we noticed that other properties (as colour brush of chart) changed without keep the value we set in the previous style. So, the style is used only to control the color of chart and the conditions, and not other properties? Or is there a mode to save a style of a chart that contains all properties?
The Chart is very complicated component and have many properties. We don't understand what you mention. Please, send us any sample with screen-shots where we could see the issue.
socotek wrote:b. We see the use of Style Chart in trial version, where it is possible set a color array. Is it possible to define and set this color array from the program that call Stimulsoft Report? Or is there a possibility to give the same color to the same category (for example, seafood in blu, beverages in yellow, ...)?
You could use Conditions of the Series for this.

There is no Group Band in the chart. Could you describe your question more detailed with images?
socotek wrote:d. (last c.) As you see in the picture below, sometimes we need to word wrap legend and series label both. It is possible? Is there a properties to set? (I can't attach the image, so I attach the pdf image)
You could set the Columns property of the Legend. Unfortunately, there is no Word Wrap property.
socotek wrote:e. If we need to create a report from a different report (so we merge different report together), we lose the page numbering.
Is it another way to numbering pages?
As we understand you join rendered pages. There is no easy way to change page numbers there. It's better to use report template with several pages.

In the report Test_TextBox.mrt attached, we have the problem to see on screen the text we put inside a text box in a particular mode, and when we print on paper we see the text in another position. It happend also in other report, where a text in a text box on screen resulted in a single row, while printed on paper we see the text on two rows.
Sorry, but we couldn't reproduce this issue. Could you describe it more detailed?
Thank you.
