BenJackGill opened a new issue, #19274:
URL: https://github.com/apache/echarts/issues/19274
### What problem does this feature solve?
The current `borderRadius` setting for a stacked bar charts does not allow
us to put a border radius on the top stacked series, whatever series that may
be.
It only allows us to put a `borderRadius` on one particular series. But
sometimes that series will have no value and will not be displayed. During
these times the top stacked series will not be rounded.
Therefore we need a method of using `borderRadius` on the top stacked
series, whatever series that may be at the time.
**Example:**
In the image below the stacked bars on the left have a blue series named
`rank1` which is currently the top stack and correctly rounded using
`borderRadius`.
But theright stacked bars do not have a value for `rank1`. So the top series
in that case is actually `rank2To5` which does not get the `borderRadius`
applied.

**Here is the above illustrated with code:**
```lang-TypeScript
const options: ECOption = {
xAxis: {
type: "time",
},
yAxis: {
type: "value",
show: false,
},
dataset: {
dimensions: [
{ name: "date", type: "time" },
{ name: "rank51Plus", type: "number" },
{ name: "rank21To50", type: "number" },
{ name: "rank11To20", type: "number" },
{ name: "rank6To10", type: "number" },
{ name: "rank2To5", type: "number" },
{ name: "rank1", type: "number" },
],
source: rankChartPoints.value,
},
series: [
{
name: "#51+",
type: "bar",
stack: "ranks",
color: mediumRedHex,
encode: {
x: "date",
y: "rank51Plus",
},
},
{
name: "#21-50",
type: "bar",
stack: "ranks",
color: orange6Hex,
encode: {
x: "date",
y: "rank21To50",
},
},
{
name: "#11-20",
type: "bar",
stack: "ranks",
color: amber7Hex,
encode: {
x: "date",
y: "rank11To20",
},
},
{
name: "#6-10",
type: "bar",
stack: "ranks",
color: lime7Hex,
encode: {
x: "date",
y: "rank6To10",
},
},
{
name: "#2-5",
type: "bar",
stack: "ranks",
color: lightGreen7Hex,
encode: {
x: "date",
y: "rank2To5",
},
},
{
name: "#1",
type: "bar",
stack: "ranks",
color: "#00b0ff",
encode: {
x: "date",
y: "rank1",
},
itemStyle: {
borderRadius: [10, 10, 0, 0], // Adding border radius here, but
sometimes this series has no value causing borderRadius to disappear
},
},
],
};
```

### What does the proposed API look like?
I propose we allow setting of the `borderRadius` outside of the `series`.
Perhaps somewhere on `yAxis` and `xAxis` which already has other style
elements.
Something like this:
```TypeScript
yAxis: {
stackedBarStyle: {
topSeriesBorderRadius: [10, 10, 0, 0]
}
},
```
```TypeScript
xAxis: {
stackedBarStyle: {
topSeriesBorderRadius: [10, 10, 0, 0]
}
},
```
