AChartEngine is a charting library for Android applications. It currently supports the following chart types: line chart area chart scatter chart time chart bar chart pie chart bubble chart doughnut chart range (high-low) bar chart dial chart / gauge combined (any combination of line, cubic line, scatter, bar, range bar, bubble) chart cubic line chart All the above supported chart types can contain multiple series, can be displayed with the X axis horizontally (default) or vertically and support many other custom features. The charts can be built as a view that can be added to a view group or as an intent, such as it can be used to start an activity. The model and the graphing code is well optimized such as it can handle and display huge number of values. AChartEngine is currently at the 1.0.0 release. New chart types will be added in the following releases. Please keep sending your feedback such as we can continually improve this library.

Based on nightly build Jan 31, 2015.
- Present interface
SHOW/HIDE AUTO GRID
setShowGrid(boolean) // X and Y
setShowGridX(boolean) // X only
setShowGridY(boolean) // Y only
SHOW/HIDE CUSTOM GRID
setShowCustomTextGrid(boolean) // X and Y
setShowCustomTextGridX(boolean) // X only
setShowCustomTextGridY(boolean) // Y only
SHOW/HIDE AUTO AXIS LABEL
setShowLabels(boolean) // X and Y, affects all, custom too!
// No singular X/Y.
SHOW/HIDE CUSTOM AXIS LABEL
// None, stuck with above.
- Problems
(1) Major.
Cannot toggle custom labels only.
Cannot toggle X and Y labels separately.
Discussion: If using custom labels, ask question why? Good chance user does not
want auto labels if using custom.
I have a descending Y axis which requires custom labels. If use undocumented
high-min/low-max approach custom labels do not show (bug?). If use custom
labels and transform data (easy) then are forced to show auto labels with my
custom labels - one descending the other ascending!
(2) Minor
Inconsistent naming: TextLabel vs CustomText. X before vs X after (less
important)
e.g.
labels: addXTextLabel(), clearXTextLabels(), removeXTextLabel()
grid: setShowCustomTextGridX()
NB. Custom text labels can be numeric, therefore "CustomLabel" better (doesn't
imply alphabetic)? But have CustomText in grid methods...
Better: addCustomLabelX(), clearCustomLabelsX(), removeCustomLabel()
- Advised best solution, ignores backward compatibility
SHOW/HIDE AUTO GRID - No Change
setShowGrid(boolean)
setShowGridX(boolean)
setShowGridY(boolean)
SHOW/HIDE CUSTOM GRID - Name change only
setShowCustomLabelGrid(boolean)
setShowCustomLabelGridX(boolean
setShowCustomLabelGridY(boolean)
SHOW/HIDE AUTO AXIS LABEL - Affects auto labels only. Add new X and Y specific.
setShowLabels(boolean)
setShowLabelsX(boolean)
setShowLabelsY(boolean)
SHOW/HIDE CUSTOM AXIS LABEL - All new.
setShowCustomLabels(boolean)
setShowCustomLabelsX(boolean)
setShowCustomLabelsY(boolean)
For others always use CustomLabel to indicate custom text/label e.g.
addCustomLabelX(), clearCustomLabelsX(), removeCustomLabel().
- Advised compromise solution, backwards compatible (99% !)
SHOW/HIDE AUTO GRID - No change
setShowGrid(boolean)
setShowGridX(boolean)
setShowGridY(boolean)
SHOW/HIDE CUSTOM GRID - No Change
setShowCustomTextGrid(boolean)
setShowCustomTextGridX(boolean)
setShowCustomTextGridY(boolean)
SHOW/HIDE AUTO AXIS LABEL - Affects auto labels only. Add new X and Y specific.
setShowLabels(boolean) // Functional change, breaks compatibility? *
setShowLabelsX(boolean)
setShowLabelsY(boolean)
* Or does it? If user isn't showing any labels then wouldn't add custom labels.
SHOW/HIDE CUSTOM AXIS LABEL - All new (Naming? Align with setShowCustomTextGrid
or addXTextLabel?)
setShowCustomLabels(boolean)
setShowCustomLabelsX(boolean)
setShowCustomLabelsY(boolean)
- Thinking bigger
Do mass general interface clean-up e.g. 'Best' solution above, and others?
Release under new namespace.

Was thinking more about this: is it simply a bug that setShowLabels(boolean)
can disable custom labels? As stated previously, if user doesn't want custom
labels they can simply not add them.
Or did someone want custom grid lines but not labels? Surely they can just add
blank as the label.
While the new methods described above are ideal, at the moment I could live
with simply stopping setShowLabels() from affecting custom labels. I will
disable all auto labels and add custom for both X and Y.
