## ChartYValueCollection class


Represents a collection of Y values for a chart series.

```cpp
class ChartYValueCollection : public System::Collections::Generic::IEnumerable<System::SharedPtr<Aspose::Words::Drawing::Charts::ChartYValue>>
```

## Methods

| Method | Description |
| --- | --- |
| [get_Count](./get_count/)() | Gets the number of items in this collection. |
| [get_FormatCode](./get_formatcode/)() | Gets or sets the format code applied to the Y values. |
| [GetEnumerator](./getenumerator/)() override | Returns an enumerator object. |
| [GetType](./gettype/)() const override |  |
| [idx_get](./idx_get/)(int32_t) | Gets or sets the Y value at the specified index. |
| [idx_set](./idx_set/)(int32_t, const System::SharedPtr\<Aspose::Words::Drawing::Charts::ChartYValue\>\&) | Gets or sets the Y value at the specified index. |
| [Is](./is/)(const System::TypeInfo\&) const override |  |
| [set_FormatCode](./set_formatcode/)(const System::String\&) | Setter for [Aspose::Words::Drawing::Charts::ChartYValueCollection::get_FormatCode](./get_formatcode/). |
| static [Type](./type/)() |  |
## Remarks


All items of the collection other than **null** must have the same [ValueType](../chartyvalue/get_valuetype/).

The collection allows only changing Y values. To add or insert new values to a chart series, or remove values, the appropriate methods of the [ChartSeries](../chartseries/) class can be used.

## Examples



Shows how to get chart series data. 
```cpp
auto doc = System::MakeObject<Aspose::Words::Document>();
auto builder = System::MakeObject<Aspose::Words::DocumentBuilder>();

System::SharedPtr<Aspose::Words::Drawing::Shape> shape = builder->InsertChart(ChartType::Column, static_cast<double>(432), static_cast<double>(252));
System::SharedPtr<Aspose::Words::Drawing::Charts::Chart> chart = shape->get_Chart();
System::SharedPtr<Aspose::Words::Drawing::Charts::ChartSeries> series = chart->get_Series()->idx_get(0);

double minValue = std::numeric_limits<double>::max();
int32_t minValueIndex = 0;
double maxValue = std::numeric_limits<double>::lowest();
int32_t maxValueIndex = 0;

for (int32_t i = 0; i < series->get_YValues()->get_Count(); i++)
{
    // Clear individual format of all data points.
    // Data points and data values are one-to-one in column charts.
    series->get_DataPoints()->idx_get(i)->ClearFormat();

    // Get Y value.
    double yValue = series->get_YValues()->idx_get(i)->get_DoubleValue();

    if (yValue < minValue)
    {
        minValue = yValue;
        minValueIndex = i;
    }

    if (yValue > maxValue)
    {
        maxValue = yValue;
        maxValueIndex = i;
    }
}

// Change colors of the max and min values.
series->get_DataPoints()->idx_get(minValueIndex)->get_Format()->get_Fill()->set_ForeColor(System::Drawing::Color::get_Red());
series->get_DataPoints()->idx_get(maxValueIndex)->get_Format()->get_Fill()->set_ForeColor(System::Drawing::Color::get_Green());

doc->Save(get_ArtifactsDir() + u"Charts.GetChartSeriesData.docx");
```
