Exact histogram intervals
Histograms can use an exact bin width or bin count, with either the sample range or a custom start and end. The preview shows the resulting bin count before creation.
Dense histogram rendering
Bins narrower than one screen pixel are now reduced into a GPU pixel-column envelope, keeping dense distributions visible without gaps or disappearing bars.
Visible, editable bin data
Calculated bins now appear as a child table beneath the source data. Start, end, center, and count values remain inspectable and editable instead of being hidden chart state.
Use existing bins
Already calculated start, end, and count columns can be used directly without re-binning. Invalid gaps, overlaps, reversed intervals, and negative counts are reported instead of guessed.
Histogram lifecycle
Bin tables and their charts are grouped clearly in the data tree, can be recreated from the table, and can be removed together. Older saved histograms migrate to the visible-bin model when opened.
Matrix selection crop
Matrix creation proposes the largest complete numeric rectangle when a selection includes blank padding or holes. The dialog shows the proposed dimensions and exact cell range before creation.
Intentional blank matrices
Keeping the full selected size is now an explicit option for creating a matrix scaffold. A scaffold cannot create a field chart until its blank values and coordinates are filled.
Heatmap and contour fields
Matrix data can drive heatmaps, contour lines, or both together. Fill, line, label, color-scale, and coordinate controls stay available from one field-chart workflow.
Typed data picking
Field cells and histogram bars can be selected on the chart. The inspector reports matrix indices and x/y/z values, or the selected bin interval and count.
