January 2020 (v5.27)

The responsive() function has been rewritten to use the standard window.matchMedia API instead of the window.onresize event. You can read more about this on the RGraph blog . This is a significant change to the responsive() function but the usage of the function has only changed marginally. Now you should list the screen size clauses from largest to smallest like this:
```
.responsive([
    {maxWidth: null,width:600,height:250,options:{marginInner: 10,textSize:12}},
    {maxWidth: 800,width:400,height:200,options:{marginInner: 5,textSize:10}}
]);
```
Otherwise the usage of the function is no different.

In both the canvas and SVG libraries the String.format() function has been extended. Previously you could do this with the function:

str        = '{1} works as a {2}';
name       = 'Richard';
occupation = 'web developer';

str.format(name, occupation);

And this:

str        = '%1 works as a %2.';
name       = 'Richard';
occupation = 'web developer';

str = str.format(name, occupation)

Now though, as well as that, you can do this too:

occupation = 'web developer';
name       = 'Richard';
str        = '{name} works as a {occupation}'.format();

All of the libraries now accommodate having the data given to them as strings as well as real JavaScript arrays. So RGraph now accommodates this type of thing:
```
new RGraph.Bar({
    id: 'cvs',
    data: '4,8,6,5,3,2,5',        // Result: [4,8,6,5,3,2,5]
    // ['5','3','7','2','4'],     // Result: [5,3,7,2,4]
    // ['4,8,6','4,5,2','4,8,6'], // Result: [[4,8,6],[4,5,2],[4,8,6]]
    options: {
    }
}).draw();
```
You should of course give RGraph real JavaScript data structures (arrays containing numbers for example) - this is simply there for ease of use purposes.
The Horizontal Bar chart now has a tooltipsHotspotYonly option so you can still get at tooltips when the value of a bar is zero.
The 3D Bar chart hotspots for tooltips are now drawn more accurately which makes clicking on the bars easier.
The CSV reader has had some aliases added to the getCol() and getRow() API functions. These are:
```
csv.row();
csv.col();
csv.column();
csv.getColumn();
```
The label labelUnitsPre labelUnitsPost labelPoint labelThousand and labelDecimals properties were added to the HorseShoe Meter.

The RGraph.redraw() API function can now accept a canvas as the argument (as well as a color) to limit the clearing to a specific canvas tag. For example:

RGraph.redraw();                // Pre-existing usage
RGraph.redraw('red');           // Pre-existing usage
RGraph.redraw(myCanvas);        // New addition
RGraph.redraw(myCanvas, 'red'); // New addition

Fixed a bug with the Bar chart grow effect when supplying data to it. It wouldn't respect a maximum Y scale value that you had set.
The properties tooltipsFormattedListType and tooltipsFormattedListItems have been added to both the canvas and SVG chart types (those that support tooltips). These two properties give you the ability to easily show HTML lists (either ordered or unordered) in your tooltips by using the %{list} macro. There are demos available of charts that use lists in tooltips in the download archive.
