ModifiedLog Scales

ModifiedLog

This release adds Plottable.Scale.ModifiedLog, which can be used the same way as a Plottable.Scale.Linear:

var yScale = new Plottable.Scale.ModifiedLog();
...

A ModifiedLog scale behaves mostly the same as a log scale, but as x approaches 0, modifiedLog(x) approaches 0 instead of -Infinity. For a more in-depth explanation, see #710.

ModifiedLog is intended as a replacement for Plottable.Scale.Log, which is very buggy due to not being able to handle 0 and negative numbers.

API changes

• Plottable.Scale.ModifiedLog class has been added, to be used the same way as any QuantitiveScale.
• Plottable.Scale.ModifiedLog.showIntermediateTicks(bool) has been added. By default, ModifiedLog only shows ticks on powers of 10, like [10, 100, 1000]. If scale.showIntermediateTicks(true) is called, it will show ticks in between, like [10, 30, 70, 100, 300, 700, 1000].
• Plottable.Scale.Log is deprecated.

Get Away From You, Martin Solveig

Minor Bugfixes

• Scale.autoDomain now deals with nonlinear scales intelligently
• All calls to console.log have been replaced with Util.Methods.warn, which is safe to use in IE9
• We now have automated cross browser testing in saucelabs

Fix CSS for Plottable tooltip to avoid conflict with blueprint

v0.20.3-hover-tooltip-1

Force Plottable Tooltips to be opaque

Demo implementation of hover tooltips for Slate

Not ready for general release.

Currently tooltips only work on VerticalBar and HorizontalBar plots. To use them, project the desired tooltip text on to "tooltip-text":

barPlot.project("tooltip-text", "x"); // displays the x value as the tooltip
barPlot.project("tooltip-text", (d: any) => String(d.x).toUpperCase); // all caps

Scale Autowarnings

QuantitiveScales now warn if their domain is being set to include invalid values

Formatters accessible from Axis.Numeric

Axis.Numeric now exposes the formatter as a getter/setter

Update Numeric Axis type signature

The Plottable.Axis.Numeric class now appropriately takes any as a formatter.

Correct Git mistakes

• BaseAxis now actually will upgrade custom format functions into custom Plottable.Formatters
• XAxis and YAxis are actually removed

Gone with the Wind

This release focuses on removal.

Component.remove and Component.detach

Previously, calling .remove on a component would not destroy the component, but would temporarily detach it from the DOM. All listeners would be maintained on the removed Component. Now, that functionality is maintained by Component.detach. Calling remove will detach the component, and additionally deregister all its listeners and make it impossible to use in the future. Using remove is the correct API point to avoid memory leaks.

Axis.XAxis and Axis.YAxis

We've removed the XAxis and YAxis classes, in favor of the more general Axis.Numeric and Axis.Category.

Bugfixes & API Cleanup

• Fixed a bug where Domainer.paddingExceptions were not handled properly if multiple plots registered the same paddingException
• LinePlot and AreaPlot now animate up from the appropriate location.
• Axis.Category will now use formatters appropriately
• Axis.Numeric no longer forces the scale to return around 10 ticks, so calling QuantitiveScale.ticks(count) will now change how many ticks exist on the axis.

API Cleanup

• Label.setText has been renamed to Label.text and converted into a getter/setter
• The Formatter.Custom constructor now takes the custom format function as the first argument, and only optionally requires precision
• Plottable now exposes a version property.

Fix version number

Fix the version number. Oh, the shame.
