Add example for color axis

[hski-github]

For the section about color https://spotfiresoftware.github.io/spotfire-mods/docs/visualization-mods/using-the-api/mod-data-views/#using-the-spotfire-color-axis I would add an example to retrieve the color. In principle it is easy to use with row.color(), but with an example it is even more obvious.

I would also add the information, that marking automatically adjusts the color - if not deactivated in the settings of the visualization -, so no need to adjust opacity manually.

Example

async function logDataView(dataView)
{
    // Print axes names
    const axes = await dataView.axes();
    console.log(axes.map(axis => axis.name).join(","));

    // Print the row values.
    const rows = await dataView.allRows();
    rows.forEach(row => {
        console.log(axes.map(axis => {
            if(axis.isCategorical){
                return row.categorical(axis.name).formattedValue()
            }
            return row.continuous(axis.name).value()
        }).join(",").concat(row.color().hexCode);

    });
}
