How to remove the right click menù on bar and to color bar and sub bar

Hello Fabrizio,

Thank you for the question.

Please find our answers below:

Removing the right-click menu.
You can use the customizeContextMenu API call and its viewType property to disable the right-click menu:

function customizeContextMenuFunction(items, data, viewType) {
  if (viewType == "charts") {
    return [];
  }
}

customizeContextMenu can be defined in two ways:

1. As a regular API call: flexmonster.customizeContextMenu(customizeFunction: Function).
2. As an initialization parameter: new Flexmonster({customizeContextMenu: customizeFunction, ...}).

Changing chart colors.
The following example shows how to change the default colors for charts, check it out on JSFiddle.
To change the sub-bar colors, you can use the customizeChartElement method:

function customizeChartElementFunction(element, data) {
  let newColor = "#ff9999"
  if (data.rows && data.rows.length > 1) {
    element.style.fill = newColor;
  }
}

You are welcome to check the following JSFiddle for reference: https://jsfiddle.net/flexmonster/vxhsw1j2/. Feel free to customize this approach for your use case. 

Please let us know if our solution helped. Looking forward to hearing from you.

Kind regards,
