FunctiontxtStat(FLG95)loads text data and make a graph of frequency against the Unicode codepoints, and returns function that returns character analysis result.

Script

• txtStat.js

How to use

1. To activate interface:var y=txtStat();
2. To get character analysis result:y();
   An object is returned as a result.

Interface

1. Textarea: a text input for analysis.

2. Color input: a color for a graph.

3. Load button; it loads text data in "Textarea" as a set of data.

4. Analyze button; it analyzes all loaded text datasets and make a graph of frequency against the Unicode
   codepoints on canvas tag. Optionally another canvas tag is also available to output.

5. Clear textarea button; it clears only "Textarea".

6. Reset loaded data button; it clears only loaded text datasets.

7. Close button; it closes this interface.

Character analysis result

This is an object returned by a function, which is returned by functiontxtStat(FLG95).
This object has 9 values

1. data: JSON formatted loaded data with a valueNindicating a cumulative frequency of text datasets.

2. results: a result of analysis.
   This is an object with 4 values

   • xMax: the max Unicode codepoint value in datasets.
   • xMin: the min Unicode codepoint value in datasets.
   • maxFreq: the max frequency.
   • range: range of datasets.

3. color: color of graph.

4. log: a timestamp.

5. xMax: the max Unicode codepoint value in loaded text datasets.
   This is an object with 4 values(x,x16,char, andxMaxFreq; see 6.xMin).

6. xMin: the min Unicode codepoint value in loaded text datasets.
   xMaxandxMin are objects with 4 values.

   • x: the Unicode codepoint value.
   • x16: the Unicode codepoint value in hexadecimal.
   • char: a character at the Unicode codepoint value.
   • xMaxFreq|xMinFreq: character frequency.

7. dx: true scale of x-axis.
   Another width-extended canvas tag is recommended when dx << 1.

8. dy: true scale of y-axis.

9. lineWidth: width of bar chart.

Optional settings

• Setting of functiontxtStat(FLG95)
FLG95: true|false; 95% of canvas width is shown when FLG95 = true.

• Setting of another canvas tag to output
  A valid id of another canvas tag can be input when Analyze button is clicked.
  Character analysis result is overwritten by result of another canvas tag when input id is valid.

• Setting of canvas width
  Width of another canvas tag can be changed when input id is valid.
