The Blazor HeatMap Chart is a graphical representation of two-dimensional data where the values are represented with gradient or solid color variations. The data points are drawn as HeatMap cells using Scalable Vector Graphics (SVG) rendering.
The Blazor HeatMap Chart can display a large volume of data and provides the best initial load performance and optimized memory usage.
The Blazor Bubble HeatMap Chart, or the matrix bubble chart, visualizes the data using the variations in bubble attributes such as size, color, and sector.
The Blazor Calendar HeatMap visualizes time series data, with each data point representing a value bound to a specific time.
Populate data in the Blazor HeatMap Chart using different axis types: numeric, category, and date-time.
Use a numeric axis to represent numeric data in a HeatMap.
Use a date-time axis to represent time series data in a HeatMap. Similarly, display dates and times as axis labels with different formats.
Use a category axis to represent non-numerical data in a HeatMap and display text labels instead of numbers.
The Blazor HeatMap Chart allows you to customize the axis elements to make an axis more readable.
Achieve RTL layout by reversing the axis labels. This swaps the higher and lower ranges of an axis.
Arrange the axes smartly by moving them to positions opposite to their default positions.
Set axis labels with regular intervals, hiding adjacent labels across all types of axes.
Rotate axis labels clockwise or counterclockwise to any desired angle.
Customize the axis label text using the available formatting options.
Customize the default appearance of a cell or data point using the available formatting options.
Toggle visibility or format the data labels to display custom text along with the cell values.
Change the borders and cell spacing by customizing the border settings.
Customize the default color settings of the HeatMap cells with gradient or solid custom colors.
Color ranges allow a color to be applied to specific ranges in heatmap cells.
Display additional information about data points in the Blazor HeatMap Chart using a legend.
Choose between a gradient pointer and a list-type legend for improving data points readability.
Place the legend anywhere in the chart area to make it fit best on a page.
This component enables paging when the legend items exceed the legend bounds. Then, each legend item can be viewed by navigating between the pages.
A legend title provides information about the HeatMap legend.
Handle missed or undefined data values with empty data points.
Display tooltips with additional information on mouse hover over data points.
