如何设置 Google 可视化动态图表的状态?

发布于 2024-10-14 08:17:01 字数 455 浏览 4 评论 0原文

我正在使用 GWT 和 Google 图表工具(又名可视化)1.1 库< GWT 的 Google API 库的 /a>。

我想显示动态图表并在 Javascript

有人知道如何设置状态吗?

I'm using GWT and the Google Chart Tools (aka Visualization) 1.1 Library of the Google API Libraries for GWT.

I want to display a Motion Chart and to set the state as possible in Javascript.

Has someone an idea how to set the state?

这里是 GWT-Getting Started 页面中稍微修改过的 MotionChart,其中数据来自 Javascript 文档。我没有测试它,所以我不确定代码是否有效。

public class SimpleViz implements EntryPoint {
              public void onModuleLoad() {
                // Create a callback to be called when the visualization API
                // has been loaded.
                Runnable onLoadCallback = new Runnable() {
                  public void run() {
                    Panel panel = RootPanel.get();

                    MotionChart chart = new MotionChart(createTable(), createOptions());

                    panel.add(chart);
                  }
                };
                VisualizationUtils.loadVisualizationApi(onLoadCallback, MotionChart.PACKAGE);
              }

              private Options createOptions() {
                Options options = Options.create();
                options.setWidth(600);
                options.setHeight(300);
                options.setTitle("My Motion Chart");

                //  Passing JSON state with escaped double quotes to options class. 
                options.setState("{\"orderedByY\":false,\"showTrails\":true,\"dimensions\":{\"iconDimensions\":[\"dim0\"]},\"yAxisOption\":\"3\",\"xZoomedIn\":false,\"time\":\"1988-04-16\",\"yZoomedIn\":false,\"xAxisOption\":\"2\",\"yZoomedDataMin\":150,\"yZoomedDataMax\":617,\"xZoomedDataMin\":300,\"uniColorForNonSelected\":false,\"xLambda\":1,\"playDuration\":15000,\"yLambda\":1,\"duration\":{\"timeUnit\":\"D\",\"multiplier\":1},\"iconType\":\"BUBBLE\",\"iconKeySettings\":[{\"trailStart\":\"1988\",\"key\":{\"dim0\":\"Apples\"}},{\"trailStart\":\"1988\",\"key\":{\"dim0\":\"Oranges\"}},{\"trailStart\":\"1988\",\"key\":{\"dim0\":\"Bananas\"}}],\"colorOption\":\"2\",\"xZoomedDataMax\":1200,\"nonSelectedAlpha\":0.4,\"orderedByX\":false,\"sizeOption\":\"_UNISIZE\"}");
                return options;
              }

              private AbstractDataTable createTable() {
                DataTable data = DataTable.create();
                    data.addColumn('string', 'Fruit');
                    data.addColumn('date', 'Date');
                    data.addColumn('number', 'Sales');
                    data.addColumn('number', 'Expenses');
                    data.addColumn('string', 'Location');
                data.addColumn(ColumnType.STRING, "Fruit");
                data.addColumn(ColumnType.DATE, "Date");
                data.addColumn(ColumnType.NUMBER, "Sales");
                data.addColumn(ColumnType.NUMBER, "Expenses");
                data.addColumn(ColumnType.STRING, "Location");
                data.addRows(6);
                 data.setValue(0, 0, "Apples");
                data.setValue(0, 1, new Date (1988,0,1));
                data.setValue(0, 2, 1000);
                data.setValue(0, 3, 300);
                data.setValue(0, 4, "East");
                 data.setValue(1, 0, "Oranges");
                data.setValue(1, 1, new Date (1988,0,1));
                data.setValue(1, 2, 1150);
                data.setValue(1, 3, 200);
                data.setValue(1, 4, "West");
                 data.setValue(2, 0, "Bananas");
                data.setValue(2, 1, new Date (1988,0,1));
                data.setValue(2, 2, 300);
                data.setValue(2, 3, 250);
                data.setValue(2, 4, "West");
                 data.setValue(3, 0, "Apples");
                data.setValue(3, 1, new Date (1989,6,1));
                data.setValue(3, 2, 1200);
                data.setValue(3, 3, 400);
                data.setValue(3, 4, "East");
                 data.setValue(4, 0, "Oranges");
                data.setValue(4, 1, new Date (1989,6,1));
                data.setValue(4, 2, 750);
                data.setValue(4, 3, 150);
                data.setValue(4, 4, "West");
                 data.setValue(5, 0, "Bananas");
                data.setValue(5, 1, new Date (1989,6,1));
                data.setValue(5, 2, 788);
                data.setValue(5, 3, 617);
                data.setValue(5, 4, "West");
                return data;
     }
}

Here is slightly modified MotionChart from GWT-Getting Started page with data from Javascript documentation. I Didn't test it so I'm not sure if the code works.

public class SimpleViz implements EntryPoint {
              public void onModuleLoad() {
                // Create a callback to be called when the visualization API
                // has been loaded.
                Runnable onLoadCallback = new Runnable() {
                  public void run() {
                    Panel panel = RootPanel.get();

                    MotionChart chart = new MotionChart(createTable(), createOptions());

                    panel.add(chart);
                  }
                };
                VisualizationUtils.loadVisualizationApi(onLoadCallback, MotionChart.PACKAGE);
              }

              private Options createOptions() {
                Options options = Options.create();
                options.setWidth(600);
                options.setHeight(300);
                options.setTitle("My Motion Chart");

                //  Passing JSON state with escaped double quotes to options class. 
                options.setState("{\"orderedByY\":false,\"showTrails\":true,\"dimensions\":{\"iconDimensions\":[\"dim0\"]},\"yAxisOption\":\"3\",\"xZoomedIn\":false,\"time\":\"1988-04-16\",\"yZoomedIn\":false,\"xAxisOption\":\"2\",\"yZoomedDataMin\":150,\"yZoomedDataMax\":617,\"xZoomedDataMin\":300,\"uniColorForNonSelected\":false,\"xLambda\":1,\"playDuration\":15000,\"yLambda\":1,\"duration\":{\"timeUnit\":\"D\",\"multiplier\":1},\"iconType\":\"BUBBLE\",\"iconKeySettings\":[{\"trailStart\":\"1988\",\"key\":{\"dim0\":\"Apples\"}},{\"trailStart\":\"1988\",\"key\":{\"dim0\":\"Oranges\"}},{\"trailStart\":\"1988\",\"key\":{\"dim0\":\"Bananas\"}}],\"colorOption\":\"2\",\"xZoomedDataMax\":1200,\"nonSelectedAlpha\":0.4,\"orderedByX\":false,\"sizeOption\":\"_UNISIZE\"}");
                return options;
              }

              private AbstractDataTable createTable() {

                    data.addColumn('string', 'Location');

                data.addColumn(ColumnType.DATE, "Date");
                data.addColumn(ColumnType.NUMBER, "Sales");

我不完全确定我理解这个问题。在您引用的文档中,有用于设置状态的部分。

本质上,您必须打开已填充的 MotionChart 可视化,操作要默认显示的实体/选项,然后从图表的 GWT 控件中获取状态字段。

http://code.google.com/intl /fr/apis/visualization/documentation/gallery/motionchart.html#Motion_Chart_initial_state

从那里,您可以通过正常例程设置选项。

I'm not entirely sure I understand the question. In the docs you referenced, there is section for setting the state.

Essentially, you have to open up the MotionChart visualization you have already populated, manipulate the entities/options you want to show up by default, and then grab the state field from GWT controls for the chart.

http://code.google.com/intl/fr/apis/visualization/documentation/gallery/motionchart.html#Motion_Chart_initial_state

From there, you can set the options via normal routine.

  1. 首先,您创建图表&创建为它们提供数据的数据表 - 使用特定应用程序所需的任何选项。
  2. 然后你创建行&使用 google 的 .addRow() 和 .addColumn() 方法的列。
  3. 填充表格并使用 .draw() 方法渲染初始图像,
  4. 最后您需要一个可以更新图像的方法。
    我创建了两个自定义函数:一个用于通过 ajax 调用获取数据,另一个用于操作现有表中的数据并定期请求额外的 .draw()。

您可以在此处查看工作演示和快速教程 - http://www .logicwizards.net/monitor-lamp-servers-wbash-php5/

我希望它有帮助......

  1. first you create your chart(s) & create the datatables that feed them - with whatever options you need for your particular application.
  2. then you create the rows & columns using google's .addRow() and .addColumn() methods.
  3. populate the table(s) and render your initial images using the .draw() method
  4. lastly you'll need a method by which you can update the image(s).
    I created two custom functions: one to get the data via an ajax call, and the other to manipulate the data in the existing tables and request an additional .draw() periodically.

You can see a working demo and a quick tutorial here -- http://www.logicwizards.net/monitor-lamp-servers-wbash-php5/

I hope it helps...
