Question

我试图制作一个图表，Y轴上有3个点，x轴上有时间。数据如下：

<CustomItem title={item.title} small={true} />

代码如下：

 const small = this.props.small;

<Text style={[styles.title]}> {title} </Text>


const styles = StyleSheet.create({
    title:{
    fontSize: small ? 10 : 20, // error here 
    fontWeight: 'bold'
    }

Answer 1

它无法将timestamp转换为定义轴上位置所需的数值。但是，你不需要这个，因为你只需要恒定的距离，正如我所理解的那样。

你可以做到

plt.xticks(np.arange(4), data["T"], rotation=30)

Answer 2

让matplotlib处理x轴上的日期怎么样，

import java.io.{BufferedOutputStream, ByteArrayInputStream, ByteArrayOutputStream}
import java.util.zip.{ZipEntry, ZipOutputStream}
import akka.stream.scaladsl.{StreamConverters}
import org.apache.commons.io.FileUtils
import play.api.mvc.{Action, Controller}

class HomeController extends Controller {
  def single() = Action {
                         Ok.sendFile(
                           content = new java.io.File("C:\\Users\\a.csv"),
                           fileName = _ => "a.csv"
                         )
                       }

  def zip() = Action {
                     Ok.chunked(StreamConverters.fromInputStream(fileByteData)).withHeaders(
                       CONTENT_TYPE -> "application/zip",
                       CONTENT_DISPOSITION -> s"attachment; filename = test.zip"
                     )
                   }

  def fileByteData(): ByteArrayInputStream = {
    val fileList = List(
      new java.io.File("C:\\Users\\a.csv"),
      new java.io.File("C:\\Users\\b.csv")
    )

    val baos = new ByteArrayOutputStream()
    val zos = new ZipOutputStream(new BufferedOutputStream(baos))

    try {
      fileList.map(file => {
        zos.putNextEntry(new ZipEntry(file.toPath.getFileName.toString))
        zos.write(FileUtils.readFileToByteArray(file))
        zos.closeEntry()
      })
    } finally {
      zos.close()
    }

    new ByteArrayInputStream(baos.toByteArray)
  }
}
