using (ExcelEngine excelEngine = new ExcelEngine())
{
//Create a worksheet.
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(1);

Property Value
Type |
---|
DataBarAxisPosition |
Examples
The position of the DataBar Axis is based on the values present in the cells, It's automatic by default. If the cells contain positve and negative values then the Axis position will be cell's middle position. If the cells contain either positive or negative values then the DataBar's axis will be based on the values. Though we have only positive elements loaded, Here we set DataBar axis to middle.
using (ExcelEngine excelEngine = new ExcelEngine())
{
//Create a worksheet.
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;

System.Boolean |
Remarks
Setting color to BorderColor property makes the HasBorder to return "True".
Examples
By default there will be no color set to BorderColor property, So HasBorder property will return "False". If we set color to BorderColor property then the HasBorder property will return "True". Here in our example, we check the HasBorder property before applying Border color and after applying Border color.
using (ExcelEngine excelEngine = new ExcelEngine())
{
//Create a worksheet.
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;

Property Value
Type |
---|
System.Boolean |
Remarks
To know more about conditional formatting type refer this link.
Examples
HasGradientFill is set to "True" by default to provide a rich formatting look to DataBars. To make the DataBars look with plain unformatted color just like the color fill of cells, we can set this property to "False".
using (ExcelEngine excelEngine = new ExcelEngine())
{
//Create a worksheet.
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(1);

Declaration
IConditionValue MaxPoint { get; }
Property Value
Type |
---|
IConditionValue |
Remarks
To customize the longest bar of DataBar we have to set values for MaxPoint property.
Examples
The longest bar of DataBar is set by defining the MaxPoint property. To do that we have to set values for Value, Type and Operator Properties. Here for example, we set "70" to Value property which sets the longest bar.
using (ExcelEngine excelEngine = new ExcelEngine())
{
//Create a worksheet.
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(1);

Property Value
Type |
---|
System.Drawing.Color |
Remarks
To customize the border color and fill color of the DataBar we can use BorderColor and BarColor properties.
Examples
To customize color for DataBar which has negative values in the cells, we have to set color for NegativeBorderColor and NegativeFillColor properties. Here in our example, to show Databar for negative values we are setting red color for NegativeFillColor property.
using (ExcelEngine excelEngine = new ExcelEngine())
{
//Create a worksheet.
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(1);

}
PercentMax
Gets or sets a value that specifies the length of the longest data bar as a percentage of cell width.
Declaration
int PercentMax { get; set; }
Property Value
Type |
---|
System.Int32 |
Remarks
To set minimum length of the DataBar refer PercentMin property.
Examples
By default the DataBar's PercentMax and PercentMin are set to 100 and 0 respectively. This allows the DataBar to begin from the starting position zero to the entire cell width. We can customize the appearance of DataBars by changing these two properties. Here for example, we set the PercentMax property's value to 80. This sets the DataBars maximum lenght to 80 percent.
using (ExcelEngine excelEngine = new ExcelEngine())
{
//Create a worksheet.
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(1);
