Using the animate() function

The RGraph animate() function is similar in operation to the jquery animate() function but instead of CSS properties, it animates RGraph configuration properties. The chart below shows you how you can use it to create your own animation effects.

The animate function has been updated to version 7 to accommodate the increased pixel space on the canvas tag if scaling is enabled (which is now on by default). This means that you shouldn't have to update the values that you pass to the function.

The animate function is an older function that was previously a part of RGraph that has now been rewritten and reinstated to RGraph. It can be used in a similar fashion to the jquery animate function but instead of animating CSS properties, it animates (numeric) RGraph properties. The example shown below uses the trace effect and then when that has finished it animates the size of the tickmarks so that they grow from nothing to their correct size. The marginInner is also animated at the same time and starts at zero and grows to 15. Here's the source code:

<script>
    new RGraph.Line({
        id: 'cvs',
        data: [4,8,6,3,5,2,4],
        options: {
            textSize: 16,
            textColor: 'black',
            xaxisLabels: ['John','Fred','Lucy','Idan','Lois','Pete','Jenn'],
            marginInner: 0,
            spline: true,
            tickmarksStyle: 'dot',
            tickmarksSize: 0,// This is the initial size of the tickmarks
        }
    }).trace({frames: 60}, function (obj)
    {
        obj.animate({
            tickmarksSize: 7,
            marginInner: 15
        });
    });
</script>

Above, the animate function is run upon completion of the trace effect, however by using method chaining you can just as easily have them run concurrently like so:

<script>
    new RGraph.Line({
        id: 'cvs',
        data: [4,8,6,3,5,2,4],
        options: {
            textSize: 16,
            textColor: 'black',
            xaxisLabels: ['John','Fred','Lucy','Idan','Lois','Pete','Jenn'],
            marginInner: 0,
            spline: true,
            tickmarksStyle: 'dot',
            tickmarksSize: 0, // This is the initial size of the tickmarks
        }
    }).trace({frames: 60}).animate({
        tickmarksSize: 7,
        marginInner: 15
    });
</script>
