If defined and `stepSize` is not specified, the step size will be rounded to this many decimal places.

* Proper tick position for right positioned axis
* Test for tick mark drawing

When the chart is responsive to the parent container, the calculations for padding assumes that the figure is in pixels so that 20% is taken to be 20 (pixels), which results in the chart exceeding the parent container. This appears to be an IE11 only issue.

#5172)

* Bug: Avoid updating Chart when `responsive: true` and Chart is hidden.

* Prevent `drawing` when width/height is invalid.

#5528)

* added 'angle' option to polar charts. image comparison test is work in progress; not currently passing

* removed unnecessary variable assignment

* code cleanup based on PR; for 'angle' option on polarCharts

* Made polar chart image comparison test pass by removing debug flag. Also explicitly marked _computeAngle as private.

* Removed visibleCount computation in polar chart

* split out code related to updating the radius in polar chart's update function, into it's own 'updateRadius' function

* made updateRadius method private

* fix linting error

* updated polar charts to read custom angles from "chart.options.elements.arc.angle" instead of "chart.options.angle"

Refactor `updateElement` and `removeHoverStyle` and fix tests.

Use `arcTo` instead of `quadraticCurveTo` (both methods have the same compatibility level) because it generates better results when the final rect is a circle but also when it's actually a rectangle and not a square. This change is needed by the datalabels plugin where the user can configure the `borderRadius` and thus generate circle from a rounded rectangle.

While the second dataset already has a label ("My Second dataset") the first dataset showed "undefined" as a label. Added a label to the first dataset object.

Bring ctx.beginPath() before switch and replace ctx.fillRect()/ctx.strokeRect() with ctx.rect()/ctx.fill() to make it consistent with the other styles. It is also preferable that helpers.canvas.roundedRect() include ctx.closePath() at the end because CanvasRenderingContext2D.rect() closes the subpath.

Get rid of ctx.closePath() for cross, crossRot, star, line and dash because these have no closed path shape, and it should be avoided that ctx.closePath() makes a round-trip path.

When 0, the min and max options was considered not being set, instead we should check for null or undefined.

Replace the old style canvas "mock" context checks by image based unit tests which are easier to maintain and allow more flexibility in the drawing logic since we are not testing the context calls but the final painted result.

Explicitly disable hardware acceleration to make image diff more stable when ran on Travis and dev machine.

Account for zero indexing of arrays when creating a name for an added dataset and remove the last dataset in the array when removing a dataset rather than removing the first.

If you attach event handlers to a container rather than directly to the canvas then the currentTarget is the container, event.target is the canvas that triggers the event. It's useful to do this if you have many charts or are creating them dynamically.

* Add test for correct handling of small numbers

* Calculate tick precision for arbitrarily small numbers

* Use scientific notation for very small tick numbers

* Calculate significant digits for exponential tick values

Wicked-Charts is a Java wrapper around Chart.js and allows users to create charts in Java using the Wicket framework. The latest version of Wicked-Charts (3.1.0) supports Chartjs and Wicket 8.
