This panel visualization allows you to graph categorical data.
Only one data frame is supported and it must have at least one string field that will be used as the category for an X or Y axis and one or more numerical fields.
Example:
Browser
Market share
Chrome
50
IE
17.5
If you have more than one numerical field the panel will show grouped bars.
If you have multiple time series or tables you first need to join them using a join or reduce transform. For example if you have multiple time series and you want to compare their last and max value add the Reduce transform and specify Max and Last as options under Calculations.
Use these options to refine your visualization.
Auto - Algology decides the bar orientation based on what the panel dimensions.
Horizontal - Will make the X axis the category axis.
Vertical - Will make the Y axis the category axis.
When the graph is vertically oriented, this setting rotates the labels under the bars. This setting is useful when bar chart labels are long and overlap.
Sets the maximum length of bar chart labels. Labels longer than the maximum length are truncated, and appended with ....
Sets the minimum spacing between bar labels.
This controls whether values are shown on top or to the left of bars.
Auto Values will be shown if there is space
Always Always show values.
Never Never show values.
Controls bar chart stacking.
Off: Bars will not be stacked.
Normal: Bars will be stacked on each other.
Percent: Bars will be stacked on each other, and the height of each bar is the percentage of the total height of the stack.
Controls the width of groups. 1 = max with, 0 = min width.
Controls the width of bars. 1 = Max width, 0 = Min width.
Controls the radius of the bars.
0 = Minimum radius
0.5 = Maximum radius
Controls if the entire surrounding area of the bar is highlighted when you hover over the bar.
Controls line width of the bars.
Controls the fill opacity bars.
Set the mode of the gradient fill. Fill gradient is based on the line color. To change the color, use the standard color scheme field option.
Gradient appearance is influenced by the Fill opacity setting.
None
No gradient fill. This is the default setting.
Opacity
Transparency of the gradient is calculated based on the values on the y-axis. Opacity of the fill is increasing with the values on the Y-axis.
Hue
Gradient color is generated based on the hue of the line color.
When you hover your cursor over the visualization, Algology can display tooltips. Choose how tooltips behave.
Single - The hover tooltip shows only a single series, the one that you are hovering over on the visualization.
All - The hover tooltip shows all series in the visualization. Algology highlights the series that you are hovering over in bold in the series list in the tooltip.
Hidden - Do not display the tooltip when you interact with the visualization.
Use an override to hide individual series from the tooltip.
Use these settings to define how the legend appears in your visualization.
List - Displays the legend as a list. This is a default display mode of the legend.
Table - Displays the legend as a table.
Hidden - Hides the legend.
Choose where to display the legend.
Bottom - Below the graph.
Right - To the right of the graph.
Choose which of the standard calculations to show in the legend. You can have more than one.
Choose which of the standard calculations to show in the legend. You can have more than one.
Enter a Value to change the size of the text on your bar chart.
Use the following field settings to refine how your axes display.
Some field options will not affect the visualization until you click outside of the field option box you are editing or press Enter.
Select the placement of the Y-axis.
Auto
Algology automatically assigns Y-axis to the series. When there are two or more series with different units, then Algology assigns the left axis to the first unit and right to the following units.
Left
Display all Y-axes on the left side.
Right
Display all Y-axes on the right side.
Hidden
Hide all axes.
To selectively hide axes, Add a field override that targets specific fields.
Set a Y-axis text label.
If you have more than one Y-axis, then you can give assign different labels with an override.
Set a fixed width of the axis. By default, Algology dynamically calculates the width of an axis.
By setting the width of the axis, data whose axes types are different can share the same display proportions. This makes it easier to compare more than one graph’s worth of data because the axes are not shifted or stretched within visual proximity of each other.
Set a Soft min or soft max option for better control of Y-axis limits. By default, Algology sets the range for the Y-axis automatically based on the dataset.
Soft min and soft max settings can prevent blips from turning into mountains when the data is mostly flat, and hard min or max derived from standard min and max field options can prevent intermittent spikes from flattening useful detail by clipping the spikes past a defined point.
You can set standard min/max options to define hard limits of the Y-axis.
