[GitHub] [echarts] biankaiwen111 opened a new issue, #17145: [Bug] 热力图在一些合法数据的情况下产生空白的图像
biankaiwen111 opened a new issue, #17145:
URL: https://github.com/apache/echarts/issues/17145
### Version
5.2.2 及之前
### Link to Minimal Reproduction
_No response_
### Steps to Reproduce
对于如下的设定，热力图可以被正确的画出来
```
option={
"dataset": [
{
"id": "raw",
"dimensions": [
"Survived",
"Pclass",
"CountOfRecords",
"Gender"
],
"source": [
[1, 3, 47, "male"],
[1, 2, 17, "male"],
[1, 1, 45, "male"],
[0, 3, 300, "male"],
[0, 2, 91, "male"],
[0, 1, 77, "male"]
]
},
{
"fromDatasetIndex": 0,
"id": "sorting",
"transform": {
"type": "sort",
"config": {
"dimension": "Pclass",
"order": "asc"
}
}
}
],
"xAxis": {
"type": "category",
"name": "Pclass",
},
"yAxis": {
"type": "category",
"name": "Survived",
},
"series": [
{
"type": "heatmap",
"datasetIndex": 1,
"encode": {
"x": "Pclass",
"y": "Survived"
}
}
],
"visualMap": [
{
"dimension": "CountOfRecords",
"min": 17,
"max": 300,
"calculable": true,
"orient": "vertical",
"bottom": "50%",
"right": "1%"
}
]
}
```
但是当我交换原数据里的某两列时(交换“Gender”到首列时)，热力图却无法被画出，我这里x,y轴是根据列名确认的。
```
option={
"dataset": [
{
"id": "raw",
"dimensions": [
"Gender",
"Survived",
"Pclass",
"CountOfRecords"
],
"source": [
["male", 1, 3, 47],
["male", 1, 2, 17],
["male", 1, 1, 45],
["male", 0, 3, 300],
["male", 0, 2, 91],
["male", 0, 1, 77]
]
},
{
"fromDatasetIndex": 0,
"id": "sorting",
"transform": {
"type": "sort",
"config": {
"dimension": "Pclass",
"order": "asc"
}
}
}
],
"xAxis": {
"type": "category",
"name": "Pclass",
},
"yAxis": {
"type": "category",
"name": "Survived",
},
"series": [
{
"type": "heatmap",
"datasetIndex": 1,
"encode": {
"x": "Pclass",
"y": "Survived"
}
}
],
"visualMap": [
{
"dimension": "CountOfRecords",
"min": 17,
"max": 300,
"calculable": true,
"orient": "vertical",
"bottom": "50%",
"right": "1%"
}
]
}
```
### Current Behavior
热力图结果为空
### Expected Behavior
热力图应该依然能正确的画出图像
### Environment
```markdown
- OS:macOS
- Browser: Chrome
- Framework:
```

Hello @biankaiwen111, please add file "value" to "encode", like this:
<img width="1353" alt="image" src="https://user-images.githubusercontent.com/32434520/171841515-0bbe2e02-9a4e-40b2-8aa7-c6cb23162d94.png">
Here is the [doc](https://echarts.apache.org/zh/option.html#series-heatmap.encode):

I hope it helps.

**TITLE**
[Bug] Heat maps produce blank images in the case of some legitimate data
**BODY**
### Version
5.2.2 and before
### Link to Minimal Reproduction
_No response_
### Steps to Reproduce
For the following settings, the heatmap can be drawn correctly
````
option={
"dataset": [
{
"id": "raw",
"dimensions": [
"Survived",
"Pclass",
"CountOfRecords",
"Gender"
],
"source": [
[1, 3, 47, "male"],
[1, 2, 17, "male"],
[1, 1, 45, "male"],
[0, 3, 300, "male"],
[0, 2, 91, "male"],
[0, 1, 77, "male"]
]
},
{
"fromDatasetIndex": 0,
"id": "sorting",
"transform": {
"type": "sort",
"config": {
"dimension": "Pclass",
"order": "asc"
}
}
}
],
"xAxis": {
"type": "category",
"name": "Pclass",
},
"yAxis": {
"type": "category",
"name": "Survived",
},
"series": [
{
"type": "heatmap",
"datasetIndex": 1,
"encode": {
"x": "Pclass",
"y": "Survived"
}
}
],
"visualMap": [
{
"dimension": "CountOfRecords",
"min": 17,
"max": 300,
"calculable": true,
"orient": "vertical",
"bottom": "50%",
"right": "1%"
}
]
}
````
But when I exchanged two columns in the original data (exchanged "Gender" to the first column), the heat map could not be drawn. Here, the x and y axes are confirmed by the column names.
````
option={
"dataset": [
{
"id": "raw",
"dimensions": [
"Gender",
"Survived",
"Pclass",
"CountOfRecords"
],

["male", 1, 3, 47],
["male", 1, 2, 17],
["male", 1, 1, 45],
["male", 0, 3, 300],
["male", 0, 2, 91],
["male", 0, 1, 77]
]
},
{
"fromDatasetIndex": 0,
"id": "sorting",
"transform": {
"type": "sort",
"config": {
"dimension": "Pclass",
"order": "asc"
}
}
}
],
"xAxis": {

"series": [

"min": 17,
"max": 300,
"calculable": true,
"orient": "vertical",
"bottom": "50%",
"right": "1%"
}
]
}
````
### Current Behavior
Heatmap result is empty
### Expected Behavior
The heatmap should still draw the image correctly
### Environment
