- Calculate the vertices of the shapes so that they are inscribed in the circle that has the radius of `pointRadius`
- Remove `translate()` and `rotate()` to fix the regression introduced by #5319
- Refactor `rectRounded` for better performance
JSON doesn't support functions which are needed to create scriptable options, so implement a very basic method to load a JavaScript file exporting the config in `module.exports`. Also rename test sources (remove the `jasmine.` prefix), cleanup `karma.conf.js` and add an example .js fixture config (bubble radius option).
* 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
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.
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.
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.
* 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"
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.
* Bugfix: Improve polyfill function of log10 to return whole powers of 10
as integer values, as it caused endless loop in IE11 in the tick
creation loop.
* Compare floating-point numbers directly instead of using unnecessary division.
Cached plugin descriptors hold a reference on the plugin options, which break if the plugin options object is replaced. That case happens when the user updates the plugin options with a new object, but also since the new config update logic (#4198) that now always clones the plugin options. The fix consists in explicitly invalidating that cache before updating the chart.
Chart.layouts seems more consistent with other service names (Chart.plugins, Chart.scales, etc.) but also more inline with the service which handle many layout (one per charts).
- issue #4572: logarithmic type if all numbers are zero browser crashes "Out of memory"
- issue #4703: [BUG] Browser unresponsive on bubble chart with logarithmic axes
When `barThickness: undefined|null` (default), we compute an optimal sample size based on the smallest tick interval reduced to prevent any bar to overlap (bar equally sized). Also added support for a special `barThickness: 'flex'` value (previous default) that globally arranges bars side by side to prevent any gap when percentage options are 1 (variable bar sizes).
- allow options to be updated in-place or as a new object
- re-merge new options and rebuild scales & tooltips
- preserve reference to old scale if id/type not changed
- related tests and new sample also added.
- update document about options update
- update doc and example
* Fix issue 4441:
- y-axis labels partially hidden due to restrictive initial fitting.
* Add regression test to linear scale
* Moved regression test from linear scale to core layout service
* In tooltip x align calculation take into account caretSize
Truncation up to caretSize pixels could happen if label text produced tooltip element with size width:
* left side tooltip: width < x and width > x - caretSize
* right side tooltip: width < chartWidth - x and width > chartWidth - x - caretSize
Default caretSize = 5, so with default configuration truncation up to 5 pixels could happen.
* avoid tooltip truncation if possible
use whole chart area for displaying tooltip
* in xAlign calculation take into account caretPadding
* add tests for tooltip truncation avoid logic
* use caretX instead of xCaret
* fix lint errors
Fix Rollup issue caused by early access of the `extend` and `inherits` helpers not yet part of the `helpers/index` import. Also added (basic) unit tests for whose methods.
