[Bar chart] Legend color markers are not displayed when a function is used for chart color

[AndreaMinato]

This issue is based on #725 that was closed after resolving the problem for all chart but bar ones.

I opened this issue because I really need that feature to work even in bar charts.

I see that in the commit that closed the issue you have added

  w.globals.colors = this.predefined()
    } else {
      w.globals.colors = w.config.colors
+
+      // if user provided a function in colors, we need to eval here
+      if (
+        w.globals.axisCharts &&
+        w.config.chart.type !== 'bar' &&
+       Array.isArray(w.config.colors) &&
+      w.config.colors.length > 0 &&
+     w.config.colors.length === w.config.series.
+     // colors & series length needs same
+   ) {
+     w.globals.colors = w.config.colors.map((c, i) =>
+       return typeof c === '
+         ? c({
+             value: w.globals.axisCharts
+               ? w.globals.series[i][0]
+                 ? w.globals.series[i][0]
+                 : 0
+               : w.globals.series[i],
+             seriesIndex: i,
+             w: w
+           })
+        : c
+    })
+  }
+}
+}

    if (w.config.theme.monochrome.enabled) {

And I'm wondering why you add the w.config.chart.type !== 'bar' condition to the clause.

I tried to run locally the apexcharts.js project to exclude that check but it's not the cause, since your response on the closed issue I believe that you know that this isn't working for bar charts and maybe you have an idea about how to fix it.

May I ask you further informations and if needed I can help you troubleshot this behaviour

Thank for your work
