An axis is innermost when it's first among those not just in its
direction, but also on its side, i.e. left/right, of the plot. So the
inArray check should be against the samePosition list, not all.
Resolves#1056.
Resolves#1032. Previously it was impossible to draw the same text,
with the same style, in two different locations, because the second
would end up using the first's cache entry, which only ended up moving
the element to a new position.
Now each cache entry holds a list of positions at which the text
appears, creating clones of the original element for each position
beyond the first.
Flot 0.7 calculated x-axis label dimensions by assigning each label a
fixed width, then measuring the height as determined by the browser. A
side-effect of this technique is that x-axis label divs received a fixed
width. The rewrite of the text system in 0.8 accidentally removed this
feature; this patch restores it.
(Realted to flot issue #1031: https://github.com/flot/flot/issues/1031)
Currently, if the user declares a custom color palette with less than 5 colors (say, n), $.extend(true, options, opts) only modifies the first n colors of the default palette and leaves the last 5-n in place. When the number of series is >n, colors are used that are not part of user-defined palette, contrary to description of colors array in API.
This line overrides the extended colors array and replaces it with exactly the user-defined colors array, when present. Afterwards, the user color palette is respected by the auto tinting/shading system for when there are more series than colors.
Resolves#1016. Initialization consists of adding the tickGenerator and
tickFormatter functions to each axis. This should happen exactly once
per plot, but since the code was previously using the processDatapoints
hook, it was called once per series. When no series were present, it
ran zero times, triggering an exception when we later checked for the
existence of the functions.
Binding to the processOptions hook ensures that the axes are always
modified once, regardless of how many series there are. The axes are
already initialized by the point the hook runs, so this change shouldn't
cause any problems.
Resolves#1000. In Flot 0.7 we only calculated tickDecimals and
tickSize once, when creating the tickGenerator for the first time. This
meant that calls to setupGrid failed to recalculate the values, as
reported in #860. #861 fixed the problem by moving calculation into
tickGenerator, but this turned out to cause a new problem, since the
function doesn't run when an explicit ticks array is provided.
This commit solves both by always recalculating the values outside of
the tickGenerator function. As far as I can tell the only reason it
wasn't done this way from the beginning was to avoid unnecessary work in
the case where tickGenerator is already provided in the options. But
the extra work is negligible, and it's actually more consistent for the
properties to always be set.
Ole's original implementation used 'middle', which I switched away from.
After a great deal of testing it turns out that 'middle' does in fact
provide the most consistent results, so we're switching back to it.
The values don't change, so there's no reason to repeat those
calculations on every redraw. The resulting code is not just faster,
but also smaller and simpler, and we no longer need to store halign in
the text info object.
The core implementation used parseInt, which was originally to catch
text values, but really only stayed due to its side-effect of flooring
the values. The canvas implementation has never rounded coordinates.
This led to various one-pixel rendering glitches between the two
implementations. I've fixed the problem by consistently rounding
coordinates to the nearest whole number.
Line height is a core font property - it can be specified as part of the
unified 'font' definition - and we therefore need to give users access
to it when they're manually defining the font.
