# How to convert a ordinal color to linear color heatmap in Anychart?

Today I was trying to create a 2d heatmap plot using Anychart libraries in android studio. I am unable to convert ordinalcolor to linearcolor. Can someone please help me on this.
Short info:
Setting up the gradle in Android studio:

```allprojects {
repositories {
jcenter()
maven { url 'https://jitpack.io' }
}
```

}

```dependencies {
implementation 'com.android.support:multidex:1.0.3'
implementation 'com.github.AnyChart:AnyChart-Android:1.1.2'
```

Heatmap creation:

```    HeatMap heatmaps = AnyChart.heatMap();
List<DataEntry> data = new ArrayList<>();
```

Heatmap data Entry:

```        for (int i = 0; i < 1; i++) {
for (int j = 0; j < nx; j++) {
for (int k = 0; k < nx; k++) {
data.add(new HeatDataEntry(j + "", k + "", Pressure[i][j][k]));
}
}
}
```

Final plot:

```   String[] strArray3 = {"#90caf9", "#ffb74d", "#d84315"};
heatmaps.colorScale().colors(strArray3);
heatmaps.data(data);
AnyChartView anyChartView = (AnyChartView) findViewById(R.id.any_chart_view);
anyChartView.setChart(heatmaps);
```

Result_heatmap_view

How can i get rid of the white spaces between each color block?
Complete code:

```        int nx=100;
int[][][] Pressure=new int[1][nx][nx];
for (int i=0;i<1;i++) {
for (int j=0;j<nx;j++) {
for (int k=0;k<nx;k++) {
Pressure[i][j][k] = 50;
}
}
}

for (int i=0;i<1;i++) {
for (int j=nx/2-5;j<=nx/2+5;j++) {
for (int k=nx/2-5;k<=nx/2+5;k++) {
Pressure[i][j][k] = 20;
}
}
}
for (int i=0;i<1;i++) {
for (int j=nx/2-3;j<=nx/2+3;j++) {
for (int k=nx/2-3;k<=nx/2+3;k++) {
Pressure[i][j][k] = 2;
}
}
}

HeatMap heatmaps = AnyChart.heatMap();
List<DataEntry> data = new ArrayList<>();

for (int i = 0; i < 1; i++) {
for (int j = 0; j < nx; j++) {
for (int k = 0; k < nx; k++) {
data.add(new HeatDataEntry(j + "", k + "", Pressure[i][j][k]));
}
}
}
String[] strArray3 = {"#90caf9", "#ffb74d", "#d84315"};
heatmaps.colorScale().colors(strArray3);
heatmaps.data(data);
AnyChartView anyChartView = (AnyChartView) findViewById(R.id.any_chart_view);
anyChartView.setChart(heatmaps);
```

```HeatMap heatmaps = AnyChart.heatMap();
