WebChartLinearDataset.ChartType **ChartType** As `ChartTypes` The various types of charts that can be created from the data set.

forsearch

WebChartLinearDataset.DataColor **DataColor** As `Color` The color to be used when drawing the graphics in the chart that represent the dataset.

forsearch

WebChartLinearDataset.Fill **Fill** As `Boolean` If `True`, the graphical object in the chart that represents the data will be filled in with a color.

forsearch

WebChartLinearDataset.Label **Label** As `String` The label that will appear in the chart with the graphics that represent the dataset.

forsearch

WebChartLinearDataset.Tag **Tag** As `Variant` A place to store data associated with the dataset. ## Method descriptions

forsearch

WebChartLinearDataset.AddRow **AddRow**(Value As `Double`) Adds the value passed to the dataset.

forsearch

WebChartLinearDataset.AddRowAt **AddRowAt**(Index As `Integer`, Value As `Double`) Adds the value passed to the dataset at the index passed.

forsearch

WebChartLinearDataset.Constructor **Constructor**(Label As `String`, DataColor As `Color`, Fill As `Boolean`, `ParamArray` Datapoints() As `Double`)

Note

`Constructors` are special methods called when you create an object with the `New` keyword and pass in the parameters above.

Creates a new WebChartLinearDataset from the values passed. This examples uses the constructor to create a new dataset and then assign it to the chart: ``` xojo Var sales() As Double = Array(345890.0, 421934, 456908, 567987) Var ds As New WebChartLinearDataset("Sales", Color.Blue, True, sales) SalesChart.AddDataset(ds) SalesChart.AddLabels("Q1", "Q2", "Q3", "Q4") ```

forsearch

WebChartLinearDataset.RemoveAllRows **RemoveAllRows** Removes all the rows (data) from the dataset.

forsearch

WebChartLinearDataset.RemoveRowAt **RemoveRowAt**(Index As `Integer`) Removes the row (data) at the index passed from the dataset.

forsearch

WebChartLinearDataset.RowAt **RowAt**(Index As `Integer`) As `Double` Returns the row value at the index passed. ## Sample code This example uses a WebChartLinearDataset to present some data in a bar chart. Because WebChartLinearDataset requires the data to be of type `Double`, when using the `Array` function you must add a decimal to one of the values so that `Array` knows to return a `Double` rather than an `Integer` array. ``` xojo Var sales() As Double = Array(345890.0, 421934, 456908, 567987) Var ds As New WebChartLinearDataset("Sales", Color.Blue, True, sales) Me.AddDataset(ds) Me.AddLabels("Q1", "Q2", "Q3", "Q4") ``` ## Compatibility Web projects on all supported operating systems. ## See also `WebChartDataset` parent class; `WebChart` control, `WebChartDataset`, `WebChartCircularDataset` and `WebChartScatterDataset` classes.
