JavaScript/jQuery Errors and Warnings API

A widget accepts an array of objects as a data source. If you try to pass anything else, the E2001 error occurs. To see an example of how to provide data for a widget, refer to the Providing Data topic.

By default, data type of arguments and values is determined automatically based on the type of values from the data source. In some cases, specifying the data type explicitly may be required. For this purpose, the argumentAxis.argumentType and valueAxis.valueType options can be used.

Similarly, the types of argument and value axes are determined automatically based on the data type, or set explicitly using the type option of the argumentAxis or valueAxis object correspondingly.

If data of a specified data type cannot be represented on an axis of a specified axis type, the E2002 error occurs. For example, if you try to represent data of a string type on an axis of a logarithmic type, you will get this error.

Data source fields must contain values of numeric, string or date-time types only. Otherwise, the E2003 error occurs.

See Also

• onIncidentOccurred

For example, this error takes place when among date-time values of a data source field, a string value occurs, and it cannot be converted into date-time type.

See Also

• onIncidentOccurred

Check that you set the valueField option to a field in the data source containing at least one positive value.

Check that data objects are not looped.

Check that each data item has the following structure:

{ source: String, target: String, weight: Number }

See Also

• onIncidentOccurred

Check that each data item has the following structure:

{ source: String, target: String, weight: Number }

See Also

• onIncidentOccurred

Check that the weight field in each data object is an integer number greater than 0.

You can find lists of acceptable series types for the Chart here and the PieChart here.

When you visualize data using several value axes on a single pane, these axes must have different names. If they do not, the E2102 occurs.

See Also

• onIncidentOccurred

This error occurs when you try to assign anything other than a callback function to options like customizeTooltip in Chart or onPointSelectionChanged in PieChart.

See Also

• onIncidentOccurred

This error may occur if you have set the logarithmBase option of a logarithmic axis (for Chart) or a logarithmic scale (for RangeSelector) incorrectly. The value assigned to this option must be an integer number greater than 1.

See Also

• onIncidentOccurred

A strip for an axis is specified by the startValue and endValue options of an object in the strips array. A constant line is specified by the value option of an object in the constantLines array. All these options accept numeric values. If you try to assign a value of another type to one of these options, the E2105 error occurs.

See Also

• onIncidentOccurred

The min and max options accept a numeric or date-time value depending on the data type. If anything else is passed, the E2106 error occurs.

See Also

• onIncidentOccurred

The startValue and endValue options accept a numeric or date-time value depending on the scale data type. If anything else is passed, the E2202 error occurs.

See Also

• onIncidentOccurred

Commonly, this error appears when either the value option or the setValue(value) method were used incorrectly. To troubleshoot, check that the range you are trying to select falls between the scale start and end values and that the type of the range values is the same as the scale type.

• onIncidentOccurred

When providing data for Chart or a chart within RangeSelector, you must specify argument and value fields for chart series. If the chart data source does not contain the specified fields, or none of their values are valid, the widget places the W2002 warning into the browser console.

See Also

• onIncidentOccurred

When dividing the Chart's axes or RangeSelector's scale, you can specify intervals for major and minor ticks. However, if these intervals appear too small, the widgets will ignore them and divide the axes or scale using default tick intervals. In addition, the W2003 warning will appear.

When a multi-pane chart is used, you can specify the pane to be used by default using the defaultPane option. The name of the pane assigned to this option must be also declared within the panes array. Otherwise, the W2101 warning appears, and the last pane declared in this array is used.

• onIncidentOccurred

Using a multi-axis chart), you should specify a value axis for each series using the series.axis option. These value axes should be declared in the valueAxis array as well. If not, a value axis with the name specified for a series will be created automatically, and the widget will place the W2102 warning into the browser console.

This warning may appear if your scenario allows for the change of the widget container's size. If so, when the size is reduced down to a minimum, which is specified by the height and width options of the adaptive layout object, accessory widget elements will be hidden. The W2103 warning, particularly, appears when the chart hides its title.

This warning may appear if your scenario allows for the change of the widget container's size. If so, when the size is reduced down to a minimum, which is specified by the height and width options of the adaptive layout object, accessory widget elements will be hidden. The W2104 warning, particularly, appears when the chart hides its legend.

This warning may appear if your scenario allows for the change of the widget container's size. If so, when the size is reduced down to a minimum, which is specified by the height and width options of the adaptive layout object, accessory widget elements will be hidden. The W2105 warning, particularly, appears when the chart hides one of the axis titles.

Specify the startValue less than the endValue.

$(function () {
    $("#gaugeContainer").dxLinearGauge({ // or dxCircularGauge
        // ...
        scale: {
            startValue: 0,
            endValue: 50
        }
    });

        startValue: 0,
        endValue: 50
    });
