Ciao Daniel, thanks, I'll dig that and let you know. Thanks again, rash* 'Daniel LaLiberte' via Google Visualization API wrote on 27/04/2015 19:46: The colors of items in the timeline chart may not be as predictable as you want  but you could instead add a 'style' role column so you could associate each item with the color you want.

In case, I could rephrase it simpler like this: if I line up in two arrays values and colors for a timeline chart, in synchronized order, why my timeline bars do not use the color they're supposed to? Is the values array passed to the timeline re-sorted somehow before displaying it?

I'm building two arrays in PHP like this, for column (bar) values and bar colors:             // holds column headers and values             $tl_series[] = array(                 array('type'=>'string', 'id'=>'Date'),                 array('type'=>'string', 'id'=>'Value'),                 array('type'=>'date', 'id'=>'Start'),                 array('type'=>'date', 'id'=>'End'),                 );             // holds bar colors             $tlc_series = array(); Then I'm adding value columns like this:             foreach ($timeline as $tl_date) {                 ....                 $tl_series[] = array($tl_label, $value, $startdate, $enddate);                 $tlc_series[] = <customized_color_hex_value>;             } The column values array is then json encoded and passed to a scripted _javascript_ function that builds the chart, like this:             function drawChart' . $chart_id . '() {                 var data = "" . CJavaScript::jsonEncode($tl_series) . ');             ... Finally, I use the $tlc_series colors array as value for timeline's colors option:             ...             'colors' => CJavaScript::jsonEncode($tlc_series),             ... I have varying number of values, from 2 up to 40, grouped by label and distributed between two dates (for those wondering, if any, I'm using YII to programmatically get data from MYSQL and draw charts). Obviously if I have N values, $tl_series will have N+1 elements while tlc_series color array will have N elements. In my thinking, element $tlc_series[0] should hold color for element $tl_series[1]. But I'm wrong: not even a simple two values array looks fine. What should I do? I tried adding a dummy first element to colors array, without success. Is the value array somehow reordered when passed to arrayToDataTable or to the chart? How can I keep value and color arrays synchronized?
