NucliOS Supported Chart Types

Category Attribute and Category Field Specifier

This property lets you customize the attribute that will be used to fill the category of the chart. Depending on the type of the chart, the category represents the data shown as the "X axis" on any axis based charts or the element on any radial based chart.

When using a grid based on a SDT, the category attribute will be disabled, and the "Category Field Specifier" property will be enabled to let you choose the SDT field containing the category data.

Series Attribute Collection and Series Field Specifier Collection

When using a chart you may want to obtain a chart that contains one or multiple series. This property lets you customize the attribute (or field if you are using an SDT based grid) used to obtain each serie's value.

For example, if you want a lines chart that shows the product sales for each product of your company, you'll want to crate a Single Serie line chart. For this, you'll have to write "ProductSales" on the "Series Attribute Collection" property. By doing this you sholud obtain a chart similar to the following:

SDPIosChartsImg06

Then, if what you want is a chart that shows your products sales compared with the product production costs and the product production units, you'll have to write each serie attribute separated by a comma: "ProductSales, ProductProductionCosts, ProductProductionUnits" on the "Series Attribute Collection" property. By doing this you sholud obtain a chart similar to the following, where each line represents one of the selected series:

SDPIosChartsImg07

Important: If you are using an Attribute based grid, for each attribute you write in the  "Series Attribute Collection" property you will have to manually add the attribute to the grid's layout

SDPIosChartsImg08

Legend Location

Legend Location is a combo property that lets you choose the position where the series legend will be placed. You can choose between "none", "top", "bottom", "float".

  • None

    The legend is not displayed.
     
  • Top

    SDPIosChartsImg09
     
  • Bottom

    SDPIosChartsImg10
     
  • Float

    SDPIosChartsImg11
     

Series Legend Collection

When legend location is set to either "top", "bottom" or "float" you have to write the legend text for each serie you want to display. When more than one serie is present, you must separate each legend with a comma.

In our example, we wrote "ProductSales, ProductProductionCosts, ProductProductionUnits" on the "Series Attribute Collection" property, so this means we'll have to write three texts on the "Series Label Collection" property, one for each serie e.g. "Sales, Cost, Units"

Show Tooltip

This property enables or disables the tooltip of the chart. The tool shows the current value and is displayed by doing a long press on any item of the chart.

Y Axis Minimum

This property allows you to customize the position of Y Axis minum value. This will change the position where the X Axis apears.

By default Y Axis Minimum is set to empty which means the minimum will be calculated depending on the series values. You can manually set a static value for the Y Axis Minimum by entering a number e.g. "10", or you can set the minimum dinamically by writing down the name of a variable which in runtime will contain the minimum value e.g. "&YAxisMin"

Y Axis Maximum

This property allows you to customize the position of Y Axis maximum value.

By default Y Axis Maximum is set to empty which means the maximum will be calculated depending on the series values. You can manually set a static value for the Y Axis Maximum by entering a number e.g. "100", or you can set the maximum dinamically by writing down the name of a variable which in runtime will contain the maximum value e.g. "&YAxisMax"

Animation Enabled

This property enables or disables the chart initial "data fill effect" animation.

Marker Type

This combo property lets you change the marker used to represent the data in the chart. You can choose between:

  • None (marker is not used)
  • Automatic
  • Circle
  • Diamond
  • Hexagon

  • Pyramid
  • Square
  • Tetragram
